A ray of light is incident on a surface of glass slab at an angle 45o. If the lateral shift produced per unit thickness is 1/√3, then the angle of refraction produced is?
A ray of light travelling in air strikes the glass surface at an angle of incidence 60∘. Find the angle of refraction in glass if refractive index of glass is 32? (given sin60∘=√32 and sin35∘=1√3)
A ray of light is incident on a glass sphere from water as shown. If μglass=32 and μwater=43. The angle of incidence so that the ray which enters the sphere does not come out of the sphere is
