The waves produced by a motor boat sailing in water are :

Options

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

Explanation

To solve the question regarding the types of waves produced by a motorboat sailing in water, we can break down the explanation into clear steps:

### Step 1: Understanding Wave Types
Waves can be classified into two main types: transverse waves and longitudinal waves. In transverse waves, the particle motion is perpendicular to the direction of wave propagation, while in longitudinal waves, the particle motion is parallel to the direction of wave propagation.

### Step 2: Analyzing Water Waves
When a motorboat moves through water, it creates disturbances in the water surface. These disturbances result in the formation of waves. As the boat moves, it pushes the water, causing it to rise and fall. This movement of water particles is perpendicular to the direction of the wave's travel, which indicates that these waves are transverse waves.

### Step 3: Identifying Sound Waves
In addition to creating waves on the water's surface, the motorboat also produces sound waves. As the boat moves, it generates sound due to the interaction of the boat with the water and air. The sound waves consist of compressions and rarefactions, where the particle motion is parallel to the direction of wave propagation, indicating that these waves are longitudinal waves.

### Step 4: Conclusion
Therefore, when a motorboat sails in water, it produces both transverse waves (on the water surface) and longitudinal waves (sound waves).

### Final Answer
The waves produced by a motorboat sailing in water are both transverse and longitudinal waves.
