Question

Two beams of red and violet color are made to pass separately through a prism (angle of the prism is 60°). In the position of minimum deviation, the angle of refraction will be
(a) 30° for both the colors
(b) greater for the violet color
(c) greater for the red color
(d) equal but not 30° for both the colors

Answer 1

Answer:

the minimum deviation=A(u-1)

here deviation will is directly promotional to refractive index of light.

here the the deviation is more in violet colour then in red

hope so helpful

good question keep it up!

Answer 2

Answer:

a is correct

Explanation:

at min deviation r1=r2

A=60÷2= 30
