Question

An unpolarized light beam is incident on a surface at an angle of incidence equal to Brewster’s angle. Then,

• A. the reflected and the refracted beams are both partially polarized
• B. the reflected beam is partially polarized and the refracted beam is completely polarized and are at right angles to each other
• C. the reflected beam is completely polarized and the refracted beam is partially polarized and are at right angles to each other
• D. both the reflected and the refracted beams are completely polarized and are at right angles to each other

Answer 1

Answer: (C)

An unpolarized light beam is incident on a surface at an angle of incidence equal to Brewster's angle. Then, the reflected beam used to polarized completely and the refracted beam used to be polarized partially. Also, both these beams used to be at right angle to each other.
