An unpolarised light beam strikes a glass surface at Brewster's angle. Then
  • A
    The refracted light will be completely polarised.
  • B
    Both the reflected and refracted light will be completely polarised.
  • ✓
    The reflected light will be completely polarised but the refracted light will be partially polarised.
  • D
    The reflected light will be partially polarised.
✓

Answer

Correct option: C.
The reflected light will be completely polarised but the refracted light will be partially polarised.
c
According to Brewster's law, reflected rays are completely polarized and refracted rays are partially polarized.
