A rectangular glass slab rests at the bottom of a trough of water. A ray of light incident on water surface at an angle of `50^(@)` passes through water into glass. What is angle of refraction in glass ? Take `mu` for water `4//3` and `mu` for glass `3//2`.

A ray of light is incident on a glass slab at an angle of 45^(@) . If refractive index of glass be 1.6, what is the angle of refraction ?

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.

A ray of light is incident on a glass slab of refractive index 1.5, making an angle of 40^(@) with the surface. The angle of refraction in glass is

A ray of light strikes the glass slab at an angle of 50^(@) . What is the angle of incidence ?

A ray of light strikes the glass slab at an angle of 50^@ .What is the angle of incidence?

A thick rectangular glass slab is kept inside a water trough. A ray of light passing through water is incident on the glass slab at an angle of 45^(@) . Calculate the angle of refraction, if refractive indices of water and glass are 1.33 and 1.45 respectively.

When a light ray enters into glass medium from water at an angle of incidence 0^(@) , what would be the angle of refraction?
