The refractive index of the material of a prism is `sqrt(2)` and the angle of the prism is `30^(@)`. One of the two refracting surfaces of the prism is made a mirror inwards, by silver coating. A beam of monochromatic light entering the prism from the other face will retrace its path (after reflection from the silvered surface) if its angle of incidence on the prism is

The refractives index of the materials of a prism is sqrt(2) and its prism angle is 30^(@) One of its refracting faces is polished .The incident beam of light will return back for the angle of incidence

A prism of refractive index sqrt(3/2) and refracting angle is 45^(@) is placed in air. One of the two refracting surface of the prism is silvered and a ray of monochromatic light enters the prism from the other face at an angle theta . If the ray retraces its path, then what is the value of theta (in degree)?
