The freshwater dolphin sends ultrasonic sound to locate its prey. If the echo off the prey is recieved by the dolphin 0.19 s after being sent, how far is the prey from the dolphin? in m
Homework Answers
let us consider the velocity in ultrasound inwater is 1500 m/s
then
distance = speed * time
d = 1500 * 0.19/ 2 = 142.5 m

A depth sounding vessel surveys the ocean bottom with ultrasonic sound that travels 1523 m/s in seawater. How deep is the water, if the time delay of the echo from the ocean floor is 6.2 s? The time delay is the time it takes the sound to travel from the sound source to the ocean floor and back to the source.
