Chapter 9 – Ray Optics
A ray of light is incident at an angle alpha on the boundary separating two transparent media. It is transmitted in other medium. If the angle incidence is increased very slightly, the ray gets reflected in the same medium. The difference between angles of deviation in the two cases will close to
