This is probably because more ordinary people who look at a rainbow (both directly or a photograph or video recording of one) will be able to see and identify the seven colors. It is customary to list indigo as a color lying between blue and violet, but it has never seemed to me that indigo is worth the dignity of being considered a separate color. – Isaac Asimov.ĭespite what Asimov said, it seems to have become generally accepted that the colors of the rainbow are seven and that they indeed include the color indigo. Most notably, science and science fiction writer and thinking Isaac Asimov (1920-1992) said the following about it: There is, however, not a universal agreement of this. So, just memorizing the first letter of each color is perhaps the best way to remember them. The white light that emits from the sun can be broken down into the 7 colors of the rainbow in order: – Mattie Stepanek What Are The 7 Colors of The Rainbow in Order? Sunset is still my favorite color, and rainbow is second. The most common mnemonic techniques are to either memorize the initials for each color in order (VIBGYOR) or turn it into a name by reversing the order ( ROY G BIV). If you’ve ever tried closing your eyes and naming those colors in the right order, you’d have found that it’s a lot harder than it may seem to get it right. In fact, most people couldn’t even name the 7 colors of the rainbow in order. But, although they are fairly common occurrences, it is remarkable how little most people actually know about rainbows. You can remember them with the acronym Roy G Biv!Īt one point or another, we have all seen a rainbow.

The result is a periodic variation in the intensity of the scattered light, a series of alternately bright and dark bands.The colors of the rainbow in order are red, orange, yellow, green, blue, indigo, violet. And at even larger angles, the beams reinforce again. When the difference equals half of the wavelength, the interference is completely destructive. As the angle increases, the two rays follow paths of substantially different lengths. At angles very close to the required rainbow angle, two paths of light through the droplet differ only slightly, and so the two rays interfere constructively. Supernumerary rainbows have a collection of bright and dark bands from violet to red due to interference. A wonderful thing is for a twinned rainbow, an inverted rainbow would be above the real one at some distance (each being separated by a common base. It depends upon the difference in size of the drops and the angle of refraction would be within 50-53° range. It depends on whether the sun is at the horizon or not, whether the environment has a fog, mist or rainīut, in case of Twinned rainbows, double reflection is supposed to happen. Even if you're above the ground, you could be able to see the colors in the same order VIBGYOR. A rainbow doesn't depend upon where ever you are.On ground, only the arc of rainbow which is above the horizon is visible.

The raindrops in between A and B all bounce different colors of light to the observer, so the observer sees the full color spectrum.Īlso If you were above the ground (at some pretty higher altitude), you would be able to see the rainbow as a full circle. All the drops surrounding B bounce light in the same way. At its height, the violet light exits at the correct angle (40°) to travel to the observer's eye. But, B is much lower in the sky, so it doesn't bounce red light to the observer. The sunlight will hit all the surrounding raindrops in the same way, so they will all bounce red light onto the observer. The other colored beams exit at a lower angle, so the observer doesn't see them. When A disperses light, only the red light exits at the correct angle (42°) to travel to the observer's eyes. Howstuffworks shows a good comparison for the image below: This 2° range is due to increasing wavelengths of different colors. For a typical rainbow, the angle of refraction at which light would enter and exit the raindrop is 40°-42° for colors in the order violet-red.

The refraction occurs twice inside a raindrop. But, it has a small difference from a prism. These images show the refraction and dispersion of light by raindrops (just like an optical prism). (Wikipedia & Howstuffworks has a pretty good article on it.) The same answer here - Refraction & Dispersion of light To understand the property of refraction through rainbows, first you could think Raindrops as falling prism-like objects.
