Concept

Problem: Suppose I1 is the intensity of light transmitted through two polarizing filters with axes at a relative angle θ, and I2 is the intensity when the axes are at a relative angle 90.0° -θ.What was the original intensity, I0, assuming the light started out unpolarized?

FREE Expert Solution

Let's take the initial light intensity to be I0.

The light is circularly polarized initially.

From the one-half rule, the irradiance of the light transmitted by the first sheet is:

Ifirst = I0/2
