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)?

A glass prism has refractive index sqrt(2) and refracting angle 30^(@) . One of the refracting surface of the prism is silvered. A beam of monchromatic light will retrace it path it its angle of incidence on the unsilvered refracting surface of the prism is
