A ray of light is incident on one face of a prism at an angle of 50^(@) with the normal . The ray is deviated by the prism through 42^(@) . What is the angle of the prism , if the angle of emergence is 51^(@) ?

The angle of a prism is 60^(@) When light is incident at an angle of 60^(@) on the prism, the angle of emerge is 40^(@) . The angle of incidence i for which the light ray will deviate the least is such that

The angle of a prism is 60^(@) When light is incident at an angle of 60^(@) on the prism, the angle of emerge is 40^(@) . The angle of incidence i for which the light ray will deviate the least is such that

A ray of light is incident at an angle of 60^(@) on one face of a 30^(@) prism . The emergent ray from the prism makes an angle of 30^(@) with the incident ray. The angle of emergence and refractive index of the material of the prism are-
