A glass prism is kept in air. The angle of deviation is plotted for the different angles of incidence of a monochromatic beam. First we experiment with red colour and then with violet colour.

View answer and explanation

Correct option: A

The maximum deviation as well as
minimum deviation is more for violet
colour

Option A (The maximum deviation as well as minimum deviation is more for violet colour) is correct because violet light has a higher refractive index than red light.

In refraction, light waves are bent on passing from one medium to the second medium, because, in the second medium A double convex lens is made of glass which has its refractive index 1,45 for violet rays and 1.50 for red rays. If the focal length for violet ray is

, the focal length for red ray will be Which light rays undergoes two internal reflection inside a raindrop, which of the rainbow is formed?
