The waves produced by a motor boat sailing in water are : a) neither longitudinal nor transverse b) both longitudinal and transverse c) only longitudinal d) only transverse

Options

A. neither longitudinal nor transverse
B. both longitudinal and transverse
C. only longitudinal
D. only transverse.

Explanation

To determine the type of waves produced by a motor boat sailing in water, we need to analyze the nature of the waves generated in this scenario.

### Step-by-Step Solution:

1. **Understanding Wave Types**:
- Waves can be classified into two main categories: longitudinal waves and transverse waves.
- Longitudinal waves are characterized by the oscillation of particles in the same direction as the wave propagation (e.g., sound waves).
- Transverse waves have oscillations that are perpendicular to the direction of wave propagation (e.g., waves on a string).

2. **Analyzing Waves in Water**:
- When a motor boat moves through water, it creates disturbances in the water surface.
- These disturbances lead to the formation of waves on the surface of the water.

3. **Identifying the Nature of Water Waves**:
- The waves created by the boat involve the movement of water particles both vertically (up and down) and horizontally (back and forth).
- The vertical movement of water particles corresponds to transverse wave motion, while the horizontal movement corresponds to longitudinal wave motion.

4. **Conclusion**:
- Since the waves produced by a motor boat involve both vertical and horizontal movements of water particles, they are classified as both longitudinal and transverse waves.
- Therefore, the correct answer to the question is option **b) both longitudinal and transverse**.

### Final Answer:
The waves produced by a motor boat sailing in water are **both longitudinal and transverse** (Option B).
