A ray of light enters a rectangular glass slab of refractive index `sqrt(3)` at an angle of incidence `60^(@)`. It travels a distance of 5cm inside the slab and emerges out of the slab. The perpendicular distance between the incident and the emergent rays is

A ray of light strikes a tansparent rectangular slab (of refractive index sqrt(2) ) At an angle of incidence of 45^(@) . The angle between the reflected and refracted rays is

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 is incident on a glass plate. The light ray travels distance of 5 cm inside the glass plate before emerging out of the glass plate. If the incident ray suffers a deviation of 30°, the perpendicular distance between incident and the emergent ray is
