Question

Assertion- A beam of white light gives a visible spectrum on passing through a glass prism.​

Answer 1

Explanation:

A hollow prism contains air in it,

so when a beam of white light is passed through it,

it does not give a spectrum

. Because light is passed from air through air, so there will be no spectrum produced.

Speed of light in gases is more than the speed of light in solids.

Prism is solid and outside the prism is air.
