Question

A light ray travels from air to an unknown transparent medium strikes at an angle of $60^{o}$ , where its speed got reduced to $2 \times 10^{8} m s^{- 1}$ . If the speed of light in air is $3 \times 10^{8} m s^{- 1}$ , the calculate the angle of refraction of the light ray inside the medium.
