Question

The refractive index of a medium is √3 . If the unpolarized light is incident on it at the polarizing angle of the medium, the angle of refraction is (A) 60° (B) 45° (C) 30° (D) 0°

Using, tan ip = √3 ∴ ip = tan-1(√3) = 60° As r= 90° - ip ∴ r = 90° -60° = 30°

Q. The refractive index of a medium is $3$ . If the unpolarized light is incident on it at the polarizing angle of the medium, the angle of refraction is

$6 0^{\circ}$

$4 5^{\circ}$

$3 0^{\circ}$

$0^{\circ}$

Using, $t an i_{p} = 3$
$∴ i_{p} = t a n^{- 1} (3) = 6 0^{\circ}$
As $r = 9 0^{\circ} - i_{p}$
$∴ r = 9 0^{\circ} - 6 0^{\circ} = 3 0^{\circ}$
