**Problem Statement:**

1. A 1024 Hz tuning fork is placed at the source position in the figure shown. What must be the smallest radius \( r \) such that a minimum will be heard at the detector? [Hint: \( v_{\text{sound}} = 343 \text{ m/s} \).]

2. If the radius is kept fixed, what other frequencies would lead to a minima?

**Diagram Explanation:**

The diagram illustrates a semi-circular path with radius \( r \) between a source and a detector. The source is located on the left side, and the detector is on a line extending horizontally to the right. The arc represents the path of sound waves traveling from the source to the detector.
