A prism having refractive index 1.414 and refracting angle 30^(@) has one of the refracting sufraces silvered .A beam of light incident on the other refracting surface will retrace its path, if the angle of incidence is

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)?
