The angle of a prism is `30^(@)`. The rays incident at `60^(@)` on one refracting face suffer a deviation of `30^(@)`. Then the angle of emergence is :

The angle of prism is 30^@ . The rays incident at 60^@ on one refracting surface suffer a deviation of 30^@ . The angle of emergence is

A ray passes through a prism of angle 60^(@) in minimum deviation position and suffers a deviation of 30^(@) . What is the angle of incidence on the prism

A ray of light is incident on one face of a prism ( m= sqrt(3) ) at an angle of 60^@ . The refracting angle of the prism is also 60^@ . Find the angle of emergence .

A ray of light is incident on one face of a prism ( m= sqrt(3) ) at an angle of 60^@ . The refracting angle of the prism is also 60^@ . Find the angle of emergence .

The refractive angle of prism is A. A ray is incident normally on one of the refracting faces of a prism and emerges out. If D be the deviation of the ray then refractive index of the material of the prism is—
