Question

what is a polarising angle​

Answer 1

Answer:

Definition of polarizing angle. : the angle at which unpolarized light or other electromagnetic radiation must be incident upon a nonmetallic surface for the reflected radiation to acquire maximum plane polarization. — called also Brewster angle.

Answer 2

Brewster's angle (also known as the polarization angle) is an angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no reflection.
