The ratio of the intensity of unpolarised incident light and polarised emergent light is :
- A 8 : 1
- B 8 : 3
- C 1 : 8
- D 3 : 8
Answer & Solution
Correct Answer
(A) 8 : 1
Step-by-step Solution
Detailed explanation
\(I_{\text{emergent}} = \frac{I_{\text{incident}}}{2} \cos^2(45^\circ) \cos^2(45^\circ)\) \(I_{\text{emergent}} = \frac{I_{\text{incident}}}{2} \left(\frac{1}{\sqrt{2}}\right)^2 \left(\frac{1}{\sqrt{2}}\right)^2\)…
