Disuss the intensity of transmitted light when a polaroid sheet is rotated between two crossed polaroids ?

Explanation

To discuss the intensity of transmitted light when a polaroid sheet is rotated between two crossed polaroids, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Setup**:
We have two crossed polaroids (let's call them P1 and P3) with their transmission axes at 90 degrees to each other. We introduce a third polaroid (P2) between them, which can be rotated at an angle θ relative to P1.

2. **Incident Intensity on P1**:
