Critical angle of the medium is 45^ . Polarising angle of incidence at the surface of the medium is

Options

  1. A45^
  2. B38^
  3. C22.5^
  4. D54.7^

Correct answer

D. 54.7^

Step-by-step solution

According to Brewster's law, = i_ p At critical angle, = 1 i_ C = 1 45^ array ll & = 2 & 2 = i_ p & i_ p = ⁻¹ 2 =54.7^ array
