Answer the following questions If the refractive index of a certain material with respect to air is 1.5, what is the refractive index of air with respect to that material ?

Answer the following questions Obtain the relation between the refractive index of the second medium with respect to the first medium and the refractive index of the first medium with respect to the second medium.

Answer the following questions What happens when a ray of light is incident normal to the interface between two media ? Draw the corresponding neat and labelled diagram.

A ray of light is incident on the surface of seperation of a medium at an angle 45^(@) and is refracted in the medium at an angle 30^(@) . What will be the velocity of light in the medium?
