An ideal Polaroid will transmit 50% of nonpolarized incident light.How much light is transmitted by two ideal Polaroids oriented with their axes parallel to each other?
A)0%
B)50%
C)100%
D)between 0% and 50%
E)between 50% and 100%

Quizplus · Accepted Answer

When two ideal Polaroids are oriented with their axes parallel to each other, the first Polaroid polarizes the light, and the second Polaroid, being aligned the same way, does not further reduce the intensity. Thus, 50% of the original nonpolarized light is transmitted through both.
