When an unpolarized light of intensity \(I_{0}\) is incident on a polarizing sheet, the intensity of the light which does not get transmitted is
- A \(\frac{1}{2} I_{0}\)
- B \(\frac{1}{4} I_{0}\)
- C zero
- D \(I_{0}\)
Answer & Solution
Correct Answer
(A) \(\frac{1}{2} I_{0}\)
Step-by-step Solution
Detailed explanation
\(I=I_{0} \cos ^{2} \theta\)
Intensity of polarized light \(=\frac{I_{0}}{2}\)
\(\therefore\) Intensity of untransmitted light
\(
=I_{0}-\frac{I_{0}}{2}=\frac{I_{0}}{2}
\)
Intensity of polarized light \(=\frac{I_{0}}{2}\)
\(\therefore\) Intensity of untransmitted light
\(
=I_{0}-\frac{I_{0}}{2}=\frac{I_{0}}{2}
\)
