a parralel beam of light falls normally on the first face of a prism of small angle.at d second face it is partly transmitted and partially reflected,the reflected beam striking at d first face again,and emergin from it in a direction making an angle 6 . 30 ' with d reversed direction....the refracted beam is found 2 have undergone a deviation of 1 . 15 ' from d original direction.Find d refractive index of d glass and d angle of prism....????
