Type: MCQ-conceptual-Medium-Class 12
Which of the following statements about the behavior of light through polaroids is correct?
A
The intensity of light passing through two aligned polaroids is zero.
B
The intensity of light reduces to 50% when passing through a single polaroid.
C
The transmitted intensity can be adjusted by changing the angle between the two polaroids.
D
Light seen through a single polaroid varies with the angle of incidence.
Correct Answer
Option B
Detailed Explanation
According to the NCERT context, the intensity coming out of a single polaroid is half of the incident intensity, and the intensity can be further controlled with a second polaroid by adjusting the angle between their pass axes. The other statements are incorrect interpretations of how polaroids function.
