Arrange air, glass and water in terms of decreasing refractive index.

Arrange air, glass and water in terms of descending order of refractive index.

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).

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.

If the absolute refractive index of glass is 1.5 and that of water is 4/3, find the refractive index of water with respect to glass.

Find the refractive index of water with respect to glass if the refractive index of water is 4/3 and the refractive index of glass is 3/2.
