A beam of light consisting of red, green, and blue colors is incident on a right-angled prism. The refractive indices of the material of the prism for the above red, green and blue wavelengths are 1.39, 1.44 and 1.47, repectively. The prism will

A

separate part of the rod colour from the green and blue colours.

B

separate all the three colours from the other two colors.

C

not separate even partially any colour from the other two colors.

D

separate part of the rod colour from the green and blue colours.

Text Solution

Verified by Experts

The correct Answer is:
A
Critical angle `sinC=(1)/(mu)`
so for`C_(R)gt45^(@),C_(G)lt45^(@),C_(B)lt45^(@)`
So total internal reflection will be for`G&B`.
