Chapter 25.7, Problem 3cTH
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.
-
c. The polarizer is slowly rotated through 360
0. As the polarizer is rotated, it is observed that the interference pattern does not change.
Consider the following incorrect prediction:
“If the direction of polarization of the polarizer were horizontal, I don’t think any light would reach the screen. In that case the light that reaches each slit would be polarized horizontally, so the light would be blocked by each of the vertical slits.”
What is the flaw in the reasoning? Explain.
