Question

When a ray is incident on a medium of refractive index n at Brewster's angle, it gets

• A. totally reflected
• B. totally absorbed
• C. circularly polarized
• D. plane polarized

Answer 1

Answer: (D)

plane polarized

Answer 2

According to Brewster?s law, when unpolarised light is incident at polarizing angle ${{i}_{p}}$ on an interface separating a rarer medium from a denser medium of refractive index $\mu$ , such that then light reflected in the rarer medium is completely polarized.
