Determine the polarising angle of the light ray moving from water of refractive index 1.33 to glass of refractive index 1.5.

Calculate the critical angle of glass and water pair. (The refractive index for glass is 1.50 and refractive index for water is 1.33).

The ratio of velocities of light in glass that in waters is ( refractive index of glass = 1.5 and refractive index of water = 1. 33)

The ratio of velocities of light in glass to that in water is (refractive index of glass = 1.5 and refactive index of water = 1.33)

The ratio of velocities of light in glass that in whater is ( refractive inde of glaass = 1.5 and refractive index of water = 1. 33)

Find the ratio of the powers of a glass lens in water and in air .Given,refractive index of glass =1.50,refractive index of water=1.33.

At the bottom of a trough filled with water a rectangular glass slab is placed. A ray of light is incident on the water surface at an angle of 30^(@) and enters the glass after passing through the water. What is the angle of refraction in glass? Given, refractive index of water is 1.33 and that of glass is 1.5.

Find the velocity of light in water, if its velocity in glass of refractive index 1.5 is 2 xx 10^(8)m//s . The refractive index of water is 1.33.
