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

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.

The refractive index of a prism is 2. this prism can have a maximum refracting angle of

The refractive index of a prism is 2. The prism can have a maximum refracting angle of

A glass prism of refractive index 1.5 is immersed in water (refractive index 4//3 ) . A light beam normally on the face AB is totally reflected to reach on the face BC if

A drop of liquid is spread over the hypotenuse of a right angled isosceles prism as shown in Fig. and a ray of light is incident normally on face AB of the prism. If refractive index of liquid is sqrt(2) , then for total internal reflection to occur, refractive index of material prism should be :

A liquid is placed in a hollow prism of angle 60^(@) . If angle of the minimum deviation is 30 what is the refractive index of the liquid?
