Question

Choose the correct statements among the following given options.

• A. Brewster's angle is independent of wavelength of light.
• B. Brewster's angle is independent of the nature of reflecting surface.
• C. Brewster's angle is different for different wavelengths.
• D. Brewsters angle depends on wavelength but not on the nature of reflecting surface.

Answer 1

The correct option is C Brewster's angle is different for different wavelengths.

Brewster's angle is an angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface,
with no reflection.
${\theta }_B=ta{n}^{-1}\left(\frac{n_2}{n_1}\right)$
$n_2$ refractive index of final medium
$n_1$ refractive index of initial medium
As different wavelength have different refractive indices the brewster angle is also different.
