Question

Ultrasonic waves emitted from above sea level with velocity in the sea water 800 m / s. If 1.6 seconds after the original wave in the transmitted wave reflected wave, it can be estimated the depth of the sea is?

Answer 1

v = 800 m/s
t = 1.6 s
S = __?

We know,
S = v t / 2
S = 800 • 1.6 / 2
S = 640 m
