Question

When unpolarized light beams are incidents in the air into glass ($n=1.5$ at polarising angle)

• A. reflected beams is $100$ polarised
• B. reflect and refracted beams are partially polarised
• C. the reason for (a) is that almost all the light is reflected
• D. all the above

Answer 1

The correct option is A reflected beams is $100$ polarised

When unpolarized light is incident at Brewster angle from one medium to another, the light that is reflected from the surface is perfectly polarized
