A laser is mounted in air, m above the edge of a large, horizontalpane of crown glass (n = 1.520), as shown in the drawing. The laser is aimed at the glass in such a way that thereflected beam is 100% polarized. Detemine the distance d between the edge of the pane and the point at which the laser beam is reflected.
