Question

The amount of light that passes through two polarizing filters depends on the angle between their polarizing axes. Is this true or false?

Answer 1

Let the intensity of light from the first polarizing filter is I_1.

The intensity of the light from the second polarizing filter is,

`I_2=I_1\cos ^2(\theta)`

where,

`\theta\text{ is the angle betw}een\text{ the polarizing filter's axes}`

Thus, the intensity of light through the passes through two polarizing filter depends on the angle between their polarizing axes.

Hence, the given statement is true.
