Brewster angle for air to water transition is (refractive index of water is `4/3`)

Brewster's angle for water is

A beam of light passing through water strikes a glass plate immersed in water . The reflected beam is completely plane polarized if the angle of inccidence is 48^@ . The refractive index of water is (4//3) . Calculate the refractive index of glass.

What will be the speed of light in water if it is given that the refractive index of water is 4/3 and the speed of light in air is 3 xx 10^(8) m/s?

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.

A lens behaves as a converging lens in air and a diverging lens in water. The refractive index of the material is (refractive index of water =1.33 )
