Solution
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 ip = µ
Clearly, wavelength affects polarising angle, and wavelength varies for various light colours.
