light:Why is sunlight white, while a rainbow has many colours?

Why is sunlight white, while a rainbow has many colours?

 The light from the Sun è.really a mixture Of many different colours or wavelengths of light. ho wavelength is ..imply the distance in which a wave repeats il•.11, Red light has a long wavolength, while violet light has a short wavelength. The light that we can see, or visible light, is actually made up of different wavelengths Mat we see as red, orange, yellow, green, blue, indigo, and violet light. These colours gradually merge into one another, and the mixture produces white light.

 As white light passes through droplets of water in the sky, the light is refracted or bent. The longer wavelengths of light are refracted more than shorter wavelengths. This causes the colours to be separated as they pass through the raindrops. The result is the rainbow of seven colours that you see in the sky!
