Question
**Wave Analysis and Calculations**

The image depicts a graph and accompanying questions related to a sinusoidal transverse wave on a string. Below is a detailed transcription and explanation for an educational context.

---

### Graph Description

**Figure 1: Snapshot at t = 0 s**

- **Axes:** 
  - Horizontal axis (x): Labeled "x [m]", ranging from 0 to 20 meters.
  - Vertical axis (y): Labeled "D [cm]", ranging from -4 cm to 4 cm.

- **Wave Pattern:** 
  - The graph shows a sinusoidal wave pattern with peaks and troughs indicating its periodic nature. The wave completes roughly one full cycle within the displayed graph.

### Accompanying Questions

1. **Wavelength and Amplitude:**
   - Determine the numerical wavelengths and amplitude from the graph, marking these values clearly.

2. **Period of the Wave:**
   - Calculate the period of the wave using relevant wave equations.

3. **Displacement Expression:**
   - Express the displacement \( D \) as a function of position \( x \) and time \( t \) in the form \( D = A \sin(kx \pm \omega t + \psi) \).
   - Determine the appropriate sign for the \( \omega t \) term.
   - Identify the phase constant \( \psi \) in radians.

4. **Vertical Displacement:**
   - Find the vertical displacement of the string at \( x = 18 \text{ m} \) at \( t = 5 \text{ s} \).

5. **Velocity of the String:**
   - Calculate the velocity of the string at \( x = 18 \text{ m} \) at \( t = 5 \text{ s} \).

### Additional Information

- The wave moves indefinitely in both positive and negative x-directions at a speed of 24 m/s.

This image and its details are designed to assist students in understanding wave properties such as displacement, wavelength, amplitude, and velocity, providing a basis for further exploration of wave mechanics.
