Concept explainers
An oceanic depth-sounding vessel surveys the ocean bottom with ultrasonic sound that travels 1530 m/s in seawater. Find the depth of the water if the time delay of the echo to the ocean floor and back is 8 seconds.
The depth of water if the time delay of the echo to the ocean floor and back is 8 s when an oceanic depth-sounding vessel surveys the ocean bottom with ultrasonic sound that travels with speed of 1530
Answer to Problem 46A
The depth of water is 6.12 km if the time delay of the echo to the ocean floor and back is 8 s.
Explanation of Solution
Given:
Speed of ultrasonic sound wave (
Time taken by sound wave (echo) to travel to the ocean floor and reflect back = 8 s
So,
Time taken by sound wave to travel to the ocean floor (
Formula used:
Depth of water (
Calculation:
Putting the values and we get;
Depth of water (
Depth of water (
Conclusion:
Thus, the depth of water is 6.12 km if the time delay of the echo to the ocean floor and back is 8 s.
