12.49: A beam of unpolarized light travpt1m 69e (q yhak38qobeling in air strikes a piece of optically flat glass at an angle of incidemy6 qp(e 9b18oah 3tqknce of $58^0$. Some of the light is reflected while the remainder is transmitted into the glass. The reflected beam is 100% polarized parallel to the surface of the glass. What is the index of refraction for the glass?
