When sunlight falls on the millions of water droplets in the air during rain or mist or near waterfalls, they undergo 'dispersion' which means scattering of light. Sunlight, 'white' light, is a combination of various colours from violet to red, colours found on a rainbow, and each colour corresponds to a specific 'wavelength' of light.
So, to put it in simple terms, sunlight is a package/bundle of various colours and when the sunlight enters a droplet, the 'bundle' is 'unwrapped' and when it leaves the water droplet on the other side, the constituents of the 'bundle' are scattered.
Think of separate colours of sunlight as different vehicles. Violet, which has the shortest wavelength of the visible spectrum of light can be compared to a cycle. Red, which has the longest wavelength of the visible spectrum can be compared to a trailer truck. Other colours in between range from motor-cycles to hatchbacks to limos to buses, from violet to red. Cycles can turn very fast whereas trailer trucks take a longer time to turn and likewise the other categories of vehicles. This can be generalised as longer vehicles take longer to turn.
This is what happens in the water droplet. Before entering the water droplet, all the vehicles (light colours) travel at the same speed. When they hit the water droplet, its like taking a turn. Cycles (violet) turns the farthest and trailer-truck (red) the least. Keep in mind that they are still travelling at the same speed. So when the light leave the droplet, violet and red and the colours in between are moving in separate directions and hence the rainbow. That is why you always see the rainbow on the other side of the sun.
You could create a rainbow yourself using a good light source and a prism, although it won't be bow-shaped.
Due to refraction of sun light through the hanging droplets of water we get a chance of viewing the attractive rainbow.
The colors of the rainbow are all present in sunlight, but mixed together. As sunlight passes through small water droplets in foggy air, the water droplets act as lenses which alter the direction of the light, and which affect different colors to different degrees, thereby breaking up the white light into a spectrum.
When sunlight shines through rain drops, the rain drops act like a prism, and the sunlight is split into the rainbow colours we see and know as a rainbow.
Spray from the waterfall launches water droplets into the air that serve to refract sunlight into a rainbow.
Refraction and total internal reflection of sun's radiation in fine droplets of water cause rainbow formation
a rainbow!
After a rain, rainbow is created when sunlight refracts millions of droplets of water. No one created the rainbow.
Uummm, no. A rainbow is only a refraction of sunlight through micro droplets of water in the atmosphere.
Yes.
A rainbow
i think becauseof a light pyrimaid
the water droplets after the rain remains in the atmosphere. When the sunlight passes through this droplets the white light of the sun splits in to 7 colors this colors forms the rainbow

The rainbow in the sky is painted by the sunlight splitting through water droplets in the air. The white light is split into its many colours, causing the rainbow.

Yes. You can create your own rainbow using a prism (and sunlight).
Right after a thunderstorm, there will still be some water droplets in the sky. When the sunlight shines on these water droplets, the white light that is reflected off the water droplets is split into seven different colours: red, orange, yellow, green, blue, violet, indigo.
