State using a neat diagram, what happens to the path of light when light ray passes from rarer to denser medium.

Assertion: White light is incident on face AB of an isosceles right angled prism as shown. Colours, for which refractive index of material of prism is more than 1.414, will be able to emerge from the face AC. Reason:Total internal reflection cannot take place for the light travelling from a rarer medium to a denser medium.
