Light falls at normal incidence on one face of a glass prism of refractive index 1.5, what will be the angle of emergence when the angle of the prism is (a) `30^(@)` (b) `50^(@)` ?

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^@

Calculate the angle of emergence (e) of ray of light incident normally on the face AC of a glass prism ABC of refractive index sqrt 3 . How will the angle of emergence change qualitatively if the ray of light emerges form the prism into a liquid of refractive index 1.3 instead of air?

A ray of light is normally incident on one face of an equilateral glass prism. Answer the following : (a) What is the angle of incidence on the first face of the prism? (b) What is the angle of refraction from the first face of the prism ? (c) What will be the angle of incidence at the second face of the prism ? (d) Will the light ray suffer minimum deviation by the prism ?

A ray of light is incident normally on one of the faces of a prism of angle 30^@ and refractive index sqrt 2 . The angle of deviation of the ray is

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