A ray of light is incident on one face of a transparent glass slab of thickness 9cm at an angle of incidence `60^@`. Lateral displacement of the ray on emerging from the opposite parallel face is `3sqrt3`cm. Refractive index of the material of slab is:

A ray of light is incident on one face of a transparent slab of thickness 15 cm. The angle of incidence is 60^(@) . If the lateral displacement of the ray on emerging from the parallel plane is 5sqrt(3) cm, the refractive index of the material of the slab is

A ray of light is incident upon a parallel sided transparent slab of thickness 9 cm at an angle of incidence 60° • If the angle of refraction is 30°, the lateral displacement of the light ray is

A ray of light is incident on a parallel slab of thickness t and refractive index n. If the angle of incidence theta is small, than the lateral displacement in the incident and emergent ray will be
