A horizontal ray hitting a prism with n=1.5, tip angle α=4o. The ray will be deflected by an angle δ=(n-1)α. The ray is further reflected by a vertical mirror. Now, if I want to make the final ray becomes horizontal again, how many degree (and in what direction) should I turn the mirror?
what is the angle of incidence when the refracted and the reflected ray are parallel to one another? does this angle depend on the wavelength of light? Ans) The angle of inciden
