Question

white light disintegrate in prism not in air why​

Answer 1

$\huge\underline\blue{Answer:-}$

Dispersion of light is the splitting of white light into its constituent colors due to the refractive index of the surface and the wavelength of the light. If the light entering the prism is not of a single colour then the emergent beam also has different colours arranged in a definite order.

Answer 2

Explanation:

Light disperse in prism because refractive index of glass is too high

it does not disperse in air because refractive index of air is not too high than that of vaccum

Secondly, light disperse when passes from one medium to another. It cannot disperse when it passes to and from same medium.
