Quizplus · Accepted Answer

When the axes of the two Polaroids are perpendicular or at right angles to each other, the entire light will be blocked, as the first Polaroid will polarize the light in one direction and the second Polaroid, being perpendicular to the first, will block all of this polarized light. Hence, light will not pass through when the axes of the two Polaroids are perpendicular to each other.
