How does the refractive index of a medium depend on its temperature ?

When a wave travels from a denser to rarer medium, then

When light is refracted into a medium

When light is refracted into a medium

Let the refractive index of a denser medium with respect to a rarer medium be n_(12) and its critical angle be theta_(c) . At an angle of incidence A when light is travelling from denser medium to rarer medium, a part of the light is reflected and the rest is refracted and the angle between reflected and refracted rays is 90^(@) , Angle A given by -
