**Chapter 34, Problem 003**

In the figure, an isotropic point source of light \( S \) is positioned at distance \( d \) from a viewing screen \( A \) and the light intensity \( I_P \) at point \( P \) (level with \( S \)) is measured. Then a plane mirror \( M \) is placed behind \( S \) at distance \( 1.3d \). By how much is \( I_P \) multiplied by the presence of the mirror?

**Diagram Explanation:**

The diagram shows a setup with the following elements:

- A point source of light labeled \( S \).
- A viewing screen labeled \( A \) with point \( P \) on it.
- A plane mirror labeled \( M \) located behind \( S \).

**Distances:**

- The distance from \( S \) to screen \( A \) is \( d \).
- The distance from the mirror \( M \) to the point source \( S \) is \( 1.3d \).

**Problem Requirements:**

- Estimate the multiplication effect of the mirror \( M \) on the light intensity \( I_P \).

**Input Section:**

- Number: [____]
- Units: [Dropdown]

*Note: Use the correct number of significant digits; the tolerance is +/-2%.*
