Why does rainbow have color?

Answer 1

Answ2. Rainbow is the name we give to the well known effect caused by the total internal reflection of light in spherical water droplets.

As Lewis Carroll has pointed out, the name of something is different from what it is, and different again from what it is known as. (But he was a logician). You'll appreciate that a rainbow is an illusion - it only has reality to the observer.

So the actual drops of water themselves have no colour, it is only because they (internally) reflect the sun's light, that we see the spectral colours. And if you ever see a double rainbow, you'll find the order of the colours reversed! Have a crack at wikipedia.org.

the rainbow has color because of a very scientifical reason that is not known quite yet...and also becasue of bananas hehehe XD!!! thanks for looking at the question i asnwered.

Answer 2

A rainbow is made by the techincally white light from the sun shining onto a raindrop which acts as a prism and seperates the colours (white = all colours).

Simples.
