The pass-axes of two polarisers were kept such that the incident unpolarised beam of intensity \(I_0\), gets completely blocked. Another polariser was introduced in between these two polarisers with its pass-axis \(60^{\circ}\) with respect to the pass-axis of the first one. The output intensity would then become
- A 0
- B \(\frac{3}{32} I_0\)
- C \(\frac{3}{16} I_0\)
- D \(\frac{3}{8} I_0\)
Answer & Solution
Correct Answer
(B) \(\frac{3}{32} I_0\)
Step-by-step Solution
Detailed explanation
Since, the pass axes of two polarisers \(P_1\) and \(P_2\) were kept such that the incident unpolarised beam of intensity \(I_0\) gets completely blocked. This means that both polarisers were kept cross (perpendicular of their pass axes) to each other. When third polariser…
