Question

a sonar signal (high frequency sound wave)send down from a ship,is reflected from a ocean floor and ditected by a microphone on a keel after transmission the speed of sound in sea water is 1500ms¹calculate the depth of the ocean​

Answer 1

Answer:

750m

Velocity of sound in water v=1500 m/s

Let the depth of sea be x.

The sound has to travel to the bottom of the sea and get reflected back to the ship itself, thus total distance traveled by the sound is 2x.

Time taken to hear an echo t=1 s

So, 2x=vt

Or 2x=1500×1

⟹ x=750 m
