A polariser and an analyser are inclined to each other at an angle \(\theta\). If the intensity of polarised light emerging from analyser is \(I_0\) then the intensity of unpolarized light incident on the polariser will be:
| 1. | \(\large\frac{I_0}{\cos ^2 \theta}\) | 2. | \(\large\frac{I_0}{2\cos ^2 \theta}\) |
| 3. | \(\large\frac{2I_0}{\cos ^2 \theta}\) | 4. | \({\large{I_0\over 2}} \cos^2\theta\) |
