Question

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

पर्याय

• depends on wavelength and is 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.

Answer 1

From Brewster's law, except for polished metallic surfaces, the polarising angle depends on wavelength and is different for different colours.  

Explanation:

According to Brewster's law, tan i_p = µ

Clearly, wavelength affects polarising angle, and wavelength varies for various light colours.
