Question

Go: A marine survey ship sends a sound
wave straight to the seabed. It
receives an echo 1.5s later. The speed
sound in seawater is 1500 m/s. Find
Se depth of the sea at this position .​

Answer 1

Answer:

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
