Question
An ultrasonic wave in water is a compression wave that travels at 1,400 m/s
A) An ultrasonic wave from a ship travels to the bottom of a lake and back in 0.16s. How deep is it at this point?
B) If an ultrasonic wave is emitted in the ocean where the ocean's depth is 3.5km, how long will the echo take to return?

2 d = 1400 * .16
d = 112 meters deep
2 d = v t
2 * 1000 * 3.5 = 1400 t
t = 5 seconds
d = 112 meters deep
2 d = v t
2 * 1000 * 3.5 = 1400 t
t = 5 seconds
