What happens to the intensity of light when it passes through two polaroids with their pass-axes at 90 degrees to each other?
A
The intensity becomes zero.
B
The intensity is halved.
C
The intensity remains the same.
D
The intensity doubles.
Correct Answer

Detailed Explanation
When light passes through two polaroids with their pass-axes at 90 degrees, no light can pass through, resulting in zero intensity. This is consistent with the behavior of light described in the context of polarizing filters.
