Light is incident normally on the short face of a 30^@-60^@-90^@ prism. A liquid is poured on the hypotenuse of the prism. If the refractive index of the prism is sqrt(3) , find the maximum refractive index of the liquid so that light is totally reflected.

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.
