A system of three polarizers \(P_1, P_2, P_3\) is set up such that the pass axis of \(P_3\) is crossed with respect to that of \(P_1\). The pass axis of \(P_2\) is inclined at \(60^o\) to the pass axis of \(P_3\). When a beam of unpolarized light of intensity \(I_0\) is incident on \(P_1\), the intensity of light transmitted by the three polarizers is \(I\). The ratio \((I_0/I)\) equals (nearly)
- A \(10.67\)
- B \(1.80\)
- C \(5.33\)
- D \(16\)
Answer & Solution
Correct Answer
(A) \(10.67\)
Step-by-step Solution
Detailed explanation
since unpolarised light falls on \(\mathrm{P}_{1}\) \(\Rightarrow\) Intensity of light transmitted from \(P_{1}=\frac{I_{0}}{2}\). Pass axis of \(\mathrm{P}_{2}\) will be at an angle of \(30^{\circ}\) with \(\mathrm{P}_{1}\) \(\therefore\) Intensity of light transmitted from…
