ACB is right-angled prism with other angles as `60^(@)` and `30^(@)` . Refractive index of the prism is 1.5. AB has thin layer of liquid on it as shown. Light falls normally on the face Ac. For total internal reflection, maximum refractive index of the liquid is

ACB is right-angled glass prism of refractive index 1.5 . /_A /_B and /_C are 60^@ 30^@ and 90^@ respectively.A thin layer of liquid is on the AB. For a ray of light which is incident normally on AC to be totally reflected at AB the refractive index of the liquid on AB should be

ABC is a right angled glass prism of refractive index, 1.5 /_A, /_B and /_C are 60^(@), 30^(@) and 90^(@) respectively. A think layer of liquid is on the AB. For a ray of light is incident normally on AC to be totally reflected at AB, the refractive index of the liquid on AB should be

The refractive index of a prism is mu . Find the maximum angle of the prism for which a ray incident on it will be transmitted through other face without total internal reflection.
