Question
The image depicts a diagram consisting of several key elements. 

1. **Horizontal Line**: A dashed horizontal line extends 5.0 meters to the right from point S to point P.

2. **Vertical Line**: From point P, a dotted vertical line extends downward to point Q, with an unspecified vertical distance labeled as Y.

3. **Points**: 
   - S: The starting point on the left side of the diagram, with two instances marked. One is 0.75 meters above the other, with an arrow indicating the vertical distance.
   - P: The end point of the horizontal line.
   - Q: The end point of the vertical line below point P.

4. **Labels**: 
   - The horizontal distance (S to P) is labeled as 5.0 meters.
   - The vertical distance from the two S points is labeled as 0.75 meters.
   - The vertical distance from P to Q is labeled as Y.

5. **Note**: Below the diagram, there is a textual note stating: "Figure not drawn to scale." 

This diagram is likely used to illustrate a physics or mathematics problem involving distance or vectors.

**Educational Exercise: Sound Wave Interference**

**Problem Description:**

Two small speakers, labeled \( S \), are positioned 0.75 meters apart. These speakers are emitting a 2500 Hz tone in phase with each other. A student stands at point \( P \), which is 5.0 meters from the midpoint between the speakers, and hears a maximum sound intensity as expected. Assume that sound reflections from nearby objects are negligible. The speed of sound is given as 343 m/s.

**Tasks:**

(a) **Calculate the wavelength of these sound waves.**

(b) **Sound Intensity Minimum:** The student moves a distance \( Y \) to point \( Q \), where the sound intensity decreases to a minimum. Calculate the shortest distance the student could have moved to observe this minimum.

(c) **Identify Another Minimum:** Determine another location on the line passing through \( P \) and \( Q \) where the student could stand to perceive another minimum, and justify the answer.

**Diagram Explanation:**

- The diagram referenced is conceptual and supports the calculations for the tasks above, illustrating the positions of the speakers and the student along with the relevant distances.
