To solve the problem, we need to apply Malus's Law, which describes how the intensity of polarized light changes as it passes through a polarizer and an analyzer. ### Step-by-Step Solution: 1. **Understanding the Initial Conditions:** - We start with an incident intensity \( I_0 \) of unpolarized light. - When this unpolarized light passes through a polarizer, the intensity of the transmitted light is reduced to half. Therefore, after passing through the polarizer, the intensity \( I \) becomes: \[ ...
