One face of a prism of refractive index `1.5` and angle `75^(@)` is covered with a liquid of refractive index `(3sqrt(2))/(4)`. What should be the angle of incidence of light on the clear face of prism for which light is just totally refracted at the liquid covered face ?

One face of a prism of refractive index 1.5 and angle 75^@ is covered with a liquid of refractive index (3 sqrt(2))/(4) . What should be the angle of incidence of light on the clear face of prism for which light is just totally reflected at the liquid covered face ?

A ray of light is incident normally on a face of the prism of refracting angle 30^(@) and refractive index sqrt(2) . Calculate the angle of deviation in degree.

Find the angle of incidence of a ray of light on one face of a 60°.prism, if the ray is just totally reflected on meeting the opposite face (refractive index of glass = 1.5).

Light falls at normal incidence on one face of a glass prism of refractive index sqrt(2) . Then the angle of emergence when the angle of the prism is 45^@

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

The refracting angle of a prism is 60^(@) and the refractive index of its material is sqrt((7)/(3)). Find the minimum angle of incidence of a ray of light falling on one refracting face of the prism such that the emerging ray will graze the other refracting face.

An equilateral prism has its faces made of a transparent fiber sheet (having refractive index = 1.25) having thickness of 1 mm. The fibre prism is filled with a liquid of refractive index sqrt(2) . Find the deviation of a light ray incident on one face of such a prism at an angle of 45° .

A glass prism of refractive index 1.5 is immersed in water of refractive index 4/3. A light ray incident normally on face AB is totally reflected at face AC if

One face of a prism with a refrective angle of 30^@ is coated with silver. A ray of light incident on another face at an angle of 45^@ is refracted and reflected from the silver coated face and retraces its path. What is the refractive index of the prism?
