A ray of light is inclined to one face of the prism at an angle of `50^@`.If the angle of the prism is `60^@` and the ray is deviated through an angle of `42^@`,lfind the angle which the emergent ray makes with the second face of the prism.

A ray of light is incident on the glass prism at an angle of 40^@ .Find the angle of emergence,if the angle of prism is 60^@ and refractive index.

A ray of light is incident on the face o a prism placed in minimum deviation position.If the anle of prism is 60^@ and deviation produced is 34^@ ,find the angle of incidence and refractive index.

Calculate the refractive index of a prism,if the angle of the prism is 60^@ and the angle of minimum deviation is 30^@ .

A ray of light is incident on a medium at polarising angle .What is the angle betweeen the relfected and refracted rays?

A ray of light is incident at an angle of 60^@ on the first face of a prism of an angle 30^@ .The ray emergingn out of the prism makes an angle of 30^@ with the incident ray as shown in Fig.3.13. . calculate the refractive index of the material of the prism.

A ray of light is incident normally on one of the faces of a prism of apex angle 30^@ and refractive index sqrt2 .Find the angle of deviation for the ray of light.

At what angle ,a ray of light will incident on one face of an equilateral prism,so that the emerget ray may graze the second surface of the prism(=1.5)?

A ray of light incident at an angle theta on a refracting face of a prism emerges from the other face normally. If the angle of the prism in 5^@ and the prism is made of a material of refractive index 1.5, the angle of incidence is:

What is the angle of incidence of a ray if the reflected ray is at an angle of 90^@ to the incident ray ?
