A ray of light is incident on a glass slab of thickness t, at an angle i,r is the angle of refraction in the glass slab. Distance travelled in the glass slab is

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 travelling inside a rectangular glass block (mu=sqrt2) is incident on the glass-air surface at an angle of incidence of 45^@ . The refractive index of air is 1. The ray will

A ray of light incident normally on a glass slab of refractive index 3/2, travels a distance of 6 cm in glass in time t. What will be the distance travelled by the ray in the same time (t) if it travels in air ?
