Question

A ship transmits a sound to the sea of depth 2250 m . if the echo is received after 3 seconds , calculate the speed of sound in water .​

Answer 1

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
