Question

Quizplus · Accepted Answer

When the axes of two polarizing filters are perpendicular to each other, the light passing through the first filter will be blocked completely by the second filter. This is because the second filter will only allow the component of light that is parallel to its axis to pass through, and since the light has already been polarized by the first filter, there is no component that is parallel to the second filter's axis. Therefore, light will not pass through a pair of polaroids when their axes are perpendicular to each other.
