Based on the velocity of sound in water, the depth of the water is 5550 m.
What is the depth of the water if a transmitted sound pulse returns an echo 7.4 seconds later?
The velocity of sound in water = 1500 m/s
Time taken to receive the echo = 7.4 seconds
- Distance travelled by sound = speed * time
Distance = 1500 * 7.4
Distance = 11100 m
Since this is a to and fro distance covered
- Depth of the water = distance travelled/ 2
Depth of water = 11100/2
Depth of water = 5550 m
Therefore, the depth of the water is 5550 m.
