Chapter 25.7, Problem 3bTH
Unpolarized red light is incident on two identical, narrow vertical slits. The photograph at right shows the interference pattern that appears on a distant screen.
-
b.A polarizer is placed directly in front of both slits, so that the light is vertically polarized before passing through the slits. It is observed that the intensity at each point on the screen decreases by a factor of two.
How can you account for the decrease in intensity at the interference maxima?
