PhysicsEasysingle choice

When the angle of incidence on a transparent material is $60 °$ , the reflected light is completely polarised. The velocity of refracted ray inside the material is

Options:

Answer:

Solution:

$μ = \tan i_{p}$
$∴ \frac{c}{v} = tan i_{p}$
$∴ v = \frac{3 \times 10^{8}}{\sqrt{3}} = \sqrt{3} \times 10^{8} m s^{- 1}$
