Polarizer and analyzer are placed in such a manner that their transmission axes are inclined at an angle `30^@` . If intensity of light emerging from the polarizer is I, then what should be the intensity of unpolarised light ?

Explanation

To solve the problem, we will use the principles of polarization and Malus's Law. Here's a step-by-step solution:

### Step 1: Understand the Initial Conditions
We have unpolarized light with an initial intensity \( I_0 \). When this unpolarized light passes through a polarizer, it becomes polarized. The intensity of the polarized light after passing through the polarizer is given by:
\[ I = \frac{I_0}{2} \]
This is because a polarizer transmits half of the intensity of unpolarized light.
