A beam of light consisting of red, green and blue colours is incident on right-angled prism as shown. The refractive index of the material of the prism for the above red, green and blue wavelengths are 1.39, 1.44 and 1.47 respectively . The prism will

A

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

B

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

C

separate all the three colurs from one another.

D

not separate even partially and colour form the other two colours.

Text Solution

Verified by Experts

The correct Answer is:
A
Difference in refractive indices of blue and green colour are less so they are seen together and red is seen separate because deviation depends on refractive index.
