The laser is armed at the glass in such a way that the reflected beam is 100% polarized. Detemine the distance d between the edge of the pane and the point at which the laser beam is reflected. Laser 0.405 m Glass pane Number Units the tolerance is +/-2% Question Attempts: Unlimited SAVE FOR LATER 12

Explanation / Answer

Such reflection occurs when incidence is at Brewster's angle.

Brewster's angle = arctan(n2/n1). n2 is for crown glass = 1.523.

The distance

d = x*n2/n1

= (0.405) * (1.523/1)

= 0.6168m
