Two polaroid `A` and `B` are set in crossed positions. A third polaroid `C` is placed between the two making `/_theta` with the pass axis of first polaroid. Write the expression for intensity of light transmitted from second polaroid. In what orientations will be transmitted intensity be (i) minimum (ii) maximum ?

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understand the setup
We have three polaroids: A, B, and C. Polaroids A and B are crossed, meaning their transmission axes are at 90 degrees to each other. Polaroid C is placed between A and B at an angle θ with respect to the transmission axis of A.

### Step 2: Apply Malus's Law
According to Malus's Law, when unpolarized light passes through a polarizer, the intensity of the transmitted light is given by:
\[ I = I_0 \cos^2(\theta) \]
