Give an example of how to calculate ocean depth

with the help of ecolocation process like most using sound wave for example ultrasound is used to calculate ocean depth it has high frequency

Explanation:

a fathometer device is used .let the downward distance travelled use to bed of the ocean by the wave be d .when these waves reflect back from the bed of ocean and received by fathometer the upward distance travelled is also d hence total distance travelled is equal to 2d. if v be the velocity of waves in water and t be the the time taken for the waves to reach back to the fathometer the from the definition of speed

speed =distance travelled÷ time taken=2d÷t

d=v×t÷2

Knowing how quickly sound travels in water allows us to assess the depth of the ocean (approximately 1,500 meters per second). Echosounding is a technique for surveying the seabed. Different frequencies of sound may be used by echosounders to learn more about the ocean.
