Answer the following question giving explanations wherever necessary.
Sound pulses emitted by dolphln travel through 20°C ocean water at a rate of 1450 m/s. In 20°C air, these pulses would travel 342.9 m/s. How can you account for this difference in speed?

Explanation

To answer the question regarding the difference in the speed of sound in water and air at the same temperature, we can break down the explanation into several steps:

### Step-by-Step Solution:

1. **Understanding Sound Propagation**:
- Sound is a mechanical wave that travels through a medium by causing the molecules of that medium to vibrate. The speed of sound depends on how quickly these vibrations can be transmitted from one molecule to another.

2. **Speed of Sound in Different Mediums**:
