When the angle of incidence on a material is 60°, the reflected light is completely polarized. The velocity of the refracted ray inside the material is (in m s-1)

Question

When the angle of incidence on a material is

60 °

, the reflected light is completely polarized. The velocity of the refracted ray inside the material is (in

m s^{- 1}

)

3 \times 10^{8}

(\frac{3}{\sqrt{2}}) \times 10^{8}

\sqrt{3} \times 10^{8}

0.5 \times 10^{8}
