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

Answer»

depends on wavelength and SI DIFFERENT for different colours
independent of wavelength and is different for different colours
independent of wavelength and is same for different colours
depends on wavelength and is same for different colours

Solution :From Brewster's LAWS `i_(p)="tan"^(-1)(mu)`
i.e., the polarising ANGLE depends on refractive INDEX and hence on wavelength and therefore is different for different colours.
