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

Options

A. depends on wavelength and is different for different colours
B. independent of wavelength and is different for different colours
C. independent of wavelength and is same for different colours
D. depends on wavelength and is same for different colours

Answer

A

Explanation

As we know, according to Brewster's law,
`tan i = mu [{:("where ,i",= " Brewster angle"),(mu,=" refractive index")]:}`
So, we can say that polarising angle depends on wavelength and is different for different colours of light.
