Rainbow is one of the optical phenomenon that occurs naturally in the earth's atmosphere. Physically, the colors commonly identified from the wavelengths. For example, the red color has a wavelength of about 625-740 nm, and blue around 435-500 nm. Set of colors that are expressed in wavelengths (usually Rainbowoften appears after the rain stops.

Report Arainbow is formed because white light enters the water droplet, where it bends in several different directions. When these bent light waves reach the other side of the water droplet, they reflect back out of the droplet instead of completely traversing the water. Since the white light is separated inside of the water, the refracted light ContohExplanation Text : Proses Terjadinya Pelangi Dalam Bahasa Inggris Sobat IBI pasti sudah tidak asing lagi dengan explanation text dalam bahasa inggris bukan? A rainbow is formed through the process pembelokkan light or on call with refraction, refraction processes at the Rainbow will be arranged in the structure and will generate a . One of nature's most splendid masterpieces is the rainbow. A rainbow is an excellent demonstration of the dispersion of light and one more piece of evidence that visible light is composed of a spectrum of wavelengths, each associated with a distinct color. To view a rainbow, your back must be to the sun as you look at an approximately 40 degree angle above the ground into a region of the atmosphere with suspended droplets of water or even a light mist. Each individual droplet of water acts as a tiny prism that both disperses the light and reflects it back to your eye. As you sight into the sky, wavelengths of light associated with a specific color arrive at your eye from the collection of droplets. The net effect of the vast array of droplets is that a circular arc of ROYGBIV is seen across the sky. But just exactly how do the droplets of water disperse and reflect the light? And why does the pattern always appear as ROYGBIV from top to bottom? These are the questions that we will seek to understand on this page of The Physics Classroom Tutorial. To understand these questions, we will need to draw upon our understanding of refraction, internal reflection and dispersion. The Path of Light Through a Droplet A collection of suspended water droplets in the atmosphere serves as a refractor of light. The water represents a medium with a different optical density than the surrounding air. Light waves refract when they cross over the boundary from one medium to another. The decrease in speed upon entry of light into a water droplet causes a bending of the path of light towards the normal. And upon exiting the droplet, light speeds up and bends away from the normal. The droplet causes a deviation in the path of light as it enters and exits the drop. There are countless paths by which light rays from the sun can pass through a drop. Each path is characterized by this bending towards and away from the normal. One path of great significance in the discussion of rainbows is the path in which light refracts into the droplet, internally reflects, and then refracts out of the droplet. The diagram at the right depicts such a path. A light ray from the sun enters the droplet with a slight downward trajectory. Upon refracting twice and reflecting once, the light ray is dispersed and bent downward towards an observer on earth's surface. Other entry locations into the droplet may result in similar paths or even in light continuing through the droplet and out the opposite side without significant internal reflection. But for the entry location shown in the diagram at the right, there is an optimal concentration of light exiting the airborne droplet at an angle towards the ground. As in the case of the refraction of light through prisms with nonparallel sides, the refraction of light at two boundaries of the droplet results in the dispersion of light into a spectrum of colors. The shorter wavelength blue and violet light refract a slightly greater amount than the longer wavelength red light. Since the boundaries are not parallel to each other, the double refraction results in a distinct separation of the sunlight into its component colors. The angle of deviation between the incoming light rays from the sun and the refracted rays directed to the observer's eyes is approximately 42 degrees for the red light. Because of the tendency of shorter wavelength blue light to refract more than red light, its angle of deviation from the original sun rays is approximately 40 degrees. As shown in the diagram, the red light refracts out of the droplet at a steeper angle toward an observer on the ground. There are a multitude of paths by which the original ray can pass through a droplet and subsequently angle towards the ground. Some of the paths are dependent upon which part of the droplet the incident rays contact. Other paths are dependent upon the location of the sun in the sky and the subsequent trajectory of the incoming rays towards the droplet. Yet the greatest concentration of outgoing rays is found at these 40-42 degree angles of deviation. At these angles, the dispersed light is bright enough to result in a rainbow display in the sky. Now that we understand the path of light through an individual droplet, we can approach the topic of how the rainbow forms. The Formation of the Rainbow A rainbow is most often viewed as a circular arc in the sky. An observer on the ground observes a half-circle of color with red being the color perceived on the outside or top of the bow. Those who are fortunate enough to have seen a rainbow from an airplane in the sky may know that a rainbow can actually be a complete circle. Observers on the ground only view the top half of the circle since the bottom half of the circular arc is prevented by the presence of the ground and the rather obvious fact that suspended water droplets aren't present below ground. Yet observers in an airborne plane can often look both upward and downward to view the complete circular bow. The circle or half-circle results because there are a collection of suspended droplets in the atmosphere that are capable concentrating the dispersed light at angles of deviation of 40-42 degrees relative to the original path of light from the sun. These droplets actually form a circular arc, with each droplet within the arc dispersing light and reflecting it back towards the observer. Every droplet within the arc is refracting and dispersing the entire visible light spectrum ROYGBIV. As described above, the red light is refracted out of a droplet at steeper angles towards the ground than the blue light. Thus, when an observer sights at a steeper angle with respect to the ground, droplets of water within this line of sight are refracting the red light to the observer's eye. The blue light from these same droplets is directed at a less steep angle and is directed along a trajectory that passes over the observer's head. Thus, it is the red light that is seen when looking at the steeper angles relative to the ground. Similarly, when sighting at less steep angles, droplets of water within this line of sight are directing blue light to the observer's eye while the red light is directed downwards at a more steep angle towards the observer's feet. This discussion explains why it is the red light that is observed at the top and on the outer perimeter of a rainbow and the blue light that is observed on the bottom and the inner perimeter of the rainbow. Rainbows are not limited to the dispersion of light by raindrops. The splashing of water at the base of a waterfall caused a mist of water in the air that often results in the formation of rainbows. A backyard water sprinkler is another common source of a rainbow. Bright sunlight, suspended droplets of water and the proper angle of sighting are the three necessary components for viewing one of nature's most splendid masterpieces.

How is Rainbow Formed?Rainbow is a natural phenomenon that is caused by the light refraction and reflections in the water drops, resulting in a spectrum of light appearing in the sky. A rainbow appears as a colorful arch. When they are caused by water and the sun, a rainbow shows up on the side of the sky that is directly facing the sun. They can become a complete loop at times, but for the average observers, only the arc will be seen. The colors in the rainbow will be the ones that can be found within the white light color spectrum as it divides. There are 7 main colors that you can see in the Rainbow which are red, orange, yellow, green, blue, indigo and violet. When the sunlight touches the water droplets, 7 colors emerge. When sunlight moving from air to water, the light colors are slowed down to various speeds - depends on their frequency. As purple light enters the raindrops, it bends at a sharp angle. On the right side of the water droplet, some light is passed back into the air, while the rest bounces back. Raindrops higher in the sky scatter the light so that only red light is visible to the observer's eyes. Droplets between red and violet reflect different colors, so the observer sees the full spectrum of colors. Sunlight striking rain in the atmosphere is refracted at the surface of the raindrop and enters the droplet. After refraction occurs, the light breaks into seven colors inside the raindrop; it is then reflected to the other side of the raindrop after traveling inside it. When the light in the raindrop refracts, a spectrum is formed to make the 7 colors of the rainbow appear. During reflection, the angle reflection is equal to the angle of incidence; this means that the reflected light travels along a set path and maintains the difference in the angle of refraction. A rainbow is a set of raindrops suspended in the atmosphere that divides sunlight into 7 colors, like a prism.

By Published Aug 9, 2021 1244 PM EDT To see how rainbows are formed, try a simple experiment. Go outside during a sun-drenched rain and look out toward the storm.

Among the most popular is the Irish folklore that leprechauns store their pot of gold at the end of a rainbow. But the truth is, rainbows can be seen only if you are in the right place at the right time. If you’ve ever seen one, consider yourself lucky. For the magical band of the colors to appear, the conditions must be just right. Which leads us to the question, how are rainbows formed exactly? Rainbows can be seen when light passes through raindrops, says Kristin Calhoun, a research scientist at the National Oceanic & Atmospheric Administration NOAA, the scientific agency focusing in part on the conditions of weather. When a person sees a rainbow, it’s really an optical illusion created by the refraction and reflection of light. An optical illusion is when you see something that appears to be something other than what is really there. When sunlight passes through raindrops, the light bends, or refracts, as it enters the droplet, and then reflects off the inside of the raindrop. This happens because the water is more dense than the air that surrounds it. As it exits the droplet, the light separates into wavelengths. Visible light is made up of various wavelengths, and each wavelength appears as a different color red, orange, yellow, green, blue, indigo and violet. Red light, for example, bends at a different angle than violet light. This is why “the person on the ground sees each color at a different location,” Calhoun says, and why rainbows look like a bow or an arc. Sometimes, however, rainbows can actually form an entire circle that you can see in a plane with the right conditions. [Related What causes a rainbow at night?] Because rainbows are created by light via raindrops, the best time to catch a rainbow is when it’s sunny and raining. “There is an even better chance when the sun is at a lower angle, so early or later in the day,” Calhoun says. If you’re trying to spot one, the key is to face the rain and have your back to the sun. With the conditions just right, Hawaii gets lots of rainbows. “Small showers and storms often form in late afternoon due to the combined effects of topography and daytime heating of the land,” Calhoun says. “These types [of] showers often produce heavy rain, but remain isolated over the center of the island.” Because rainbows are optical illusions, they’re not located at a specific distance. The location is relative to the person. That means there’s no chance you’ll ever find that pot of gold. explanation text explanation texts explanation text year 4 explanation text year 2 explanation text year 3 explanation text features explanation text year 5 explanation text comprehension explanation text year 6 features of an explanation text explanation text examples explanation text template explanation text year 1 wagoll explanation texts explanation text ks1 explanation text checklist explanation text planning sheet year 2 explanation text year 4 explanation text water cycle explanation text Filters Filters Refine by Age 0 - 5 years oldEYFS 5 - 6 years oldYear 1 6 - 7 years oldYear 2 7 - 8 years oldYear 3 8 - 9 years oldYear 4 9 - 10 years oldYear 5 10 - 11 years oldYear 6 11 - 14 years oldYear 7 - Year 9 14+ years oldYear 10+ Free Newest Refine Country England Resources Refine by Type Planning Assessment Resource Packs Lesson Teaching Packs Activity Sheets, Writing Frames & Templates PowerPoints, Flipcharts & eBooks Visual Aids Activities & Games Display Class Management Languages Adult Guidance Twinkl Go Interactive & Online Games Refine by Language All languages English فارسی ಕನ್ನಡ Afrikaans Azərbaycan Bahasa Indonesia Bokmål Bosanski Català Čeština Chichewa Cymraeg Dansk Deutsch Eesti English Australian English Canadian English Malaysia English New Zealand English Nigerian English South African English United States Español Español Latino Esperanto Euskal Français Gaeilge Gaelic Galego Hausa Hrvatski Icelandic Igbo IsiXhosa Italiano Jawa Kiswahili Kreyòl Ayisyen Latinae Latvijas Lietuvos Magyar Malagasy Malay Malti Nederlands O'Zbekiston Pilipino Polski Português Português Brasil Română Samoa Sesotho Shqiptar Slovenski Slovenský Soomaali Sunda Suomalainen Svensk Te Reo Maori Tiếng Việt Türk Turkmen Yorùbá Zulu Ελληνικά Беларускі Български Македонски Монгол Русский Српски Тоҷикистон Українська црногорски / Montenegrin Қазақ Հայերեն ייִדיש עִברִית اردو العربية नेपाली मराठी हिंदी বাঙালি ਪੰਜਾਬੀ ਦੇ ગુજરાતી தமிழ் తెలుగు മലയാളം සිංහල ไทย ລາວ မြန်မာ ქართული ភាសាខ្មែរ 中文简体 Simplified Chinese 中文繁體 Traditional Chinese 日本語 한국어 Clear all Apply Explanation Text Examples 27 reviews Last downloaded on LKS2 Explanation Writing Display Posters 11 reviews Last downloaded on KS2 Rainbow Facts PowerPoint 2 reviews Last downloaded on Filter results 0 - 5 years oldEYFS 5 - 6 years oldYear 1 6 - 7 years oldYear 2 7 - 8 years oldYear 3 8 - 9 years oldYear 4 9 - 10 years oldYear 5 10 - 11 years oldYear 6 11 - 14 years oldYear 7 - Year 9 14+ years oldYear 10+ Free Newest Filter country England Resources Refine by language Refine by Type Planning Assessment Resource Packs Lesson Teaching Packs Activity Sheets, Writing Frames & Templates PowerPoints, Flipcharts & eBooks Visual Aids Activities & Games Display Class Management Languages Adult Guidance Twinkl Go Interactive & Online Games Explore more than 3 "How Rainbows Are Formed Explanation Text" resources for teachers, parents and pupils . . ...
