Multiple choice polarisation of light polarisation wave optics optics physics

The angle of incidence at which reflected light is totally polarized form aim is :

  1. $\sin ^ { - 1 } ( n )$
  2. $\sin ^ { - 1 } \left( \frac { 1 } { n } \right)$
  3. $\tan ^ { - 1 } \left( \frac { 1 } { n } \right)$
  4. $\tan ^ { - 1 } ( n )$

D Correct answer
Explanation

Brewster's law states that the angle of incidence i for which reflected light is totally polarized is given by tan(i) = n, where n is the refractive index.
