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)?
