# 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
