A ray of light passing through water struck the water-glass interface making an angle 50 degrees with the interface. If the refractive index of water is 1.33 and the refractive index of glass is 1.6, find the angle of refraction of the light in glass.

A ray of ligt makes an angle of 62.0 with the surface of a plate ofglass having a refractive index of 1.47.
a) The angle of refraction in the glass is ____________
b) The speed of light in the glass is ________________

A beam of light enters from air to glass. If the speed of light in air is 3 x 10^8 m/s and in glass is 2 x 10^8 m/s, calculate the refractive index of glass with respect to air.
