Answer:
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
