Three polarizing filters are stacked, with the polarizing axis of the second and third filters at angles of 24.0 and 62.0°, respectively, to that of the first. If unpolarized light is incident on the stack, the light has an intensity of 69.5 W/cm² after it passes through the stack. Part A If the incident intensity is kept constant but the second polarizer is removed, what is the intensity of the light after it has passed through the stack?

The answer is no 37.65... I have used one question already on this problem, and the expert got the solution wrong 

### Educational Content on Polarizing Filters

**Description:**

Three polarizing filters are stacked together. The polarizing axis of the second filter is angled at 24.0° and the third filter at 62.0°, both relative to the first filter. Unpolarized light incident on this stack results in an intensity of 69.5 W/cm² after passing through the entire setup.

**Problem Statement (Part A):**

If the intensity of light incident on the stack remains constant, but the second polarizer is removed, determine the intensity of the light after it passes through the remaining filters.

**Instructions:**

- Express your answer in units of W/cm².

**Input Box:**

- A field is provided to calculate and input the light intensity (I = Value W/cm²).

**Action Buttons:**

- **Submit:** Submit your response.
- **Previous Answers:** Review past responses.
- **Request Answer:** Request the correct solution.

**Visual Elements:**

There is no graph or diagram, but the problem is logically structured to guide the student in solving the intensity calculation through polarizing filters using knowledge of Malus's Law and angles involved in polarization.
