In the given situation, for what value of `i`, the incidence ray will retrace its initial path.

If one face of a prism angle 30^(@) and mu=sqrt( 2) is silvered, the incident ray retraces its initial path. What is the angle of incidence ?

For the situations shown in figure, determine the angle by which the mirror should be rotated, so that the light ray will retrace its path after refraction through the prism and reflection from the mirror?

A prism has refracting angle 30^(@) and mu = 2 . One of the mat surface of the prism is polished to make it reflecting. Find the incidence angle of a light ray on other mat surface of prism so that after reflection the ray will retrace the path of incident ray.
