From Brewster's law, except for polished metallic surfaces, the polarising angle

A

depends on wavelength and is different for different colours

B

independent on wavelength and is different for different colours

C

independent on wavelength and is the same for different colours

D

depends on wavelength and is the same for different colours

Text Solution

Verified by Experts

The correct Answer is:
A
Brewster's law `mu= tan i` . As `mu` depends upon the wavelength , the polarising angle also depends upon the wavelength and it is different for different colours.
