Question

Quizplus · Accepted Answer

When two Polaroids are oriented with their axes at 45 degrees to each other, some light will pass through both, but it will be dimmer than if the Polaroids were oriented with their axes parallel to each other. This is because the second Polaroid only allows the component of light polarized along its axis to pass, which is less than the total light incident on it due to the 45-degree orientation difference.
