Question

A Sonar apparatus in a ship sends out a signal vertically downwards The signal returns after 1.6 s find the depth of the sea The velocity of sound in water=1500 m/s​

Answer 1

Answer:

The depth of the sea is 1200 m.

Explanation:

Given:

Velocity of sound in water v= 1500 m/ s

Let the depth of sea = x m.

The sound has to travel to the bottom of the sea and get reflected back to the ship itself.

Thus total distance travel by the sound = 2x m.

Time taken to hear an echo t = 1.6 s.

So, Distance = velocity × time

           2x = 1500 × 1.6

              x = 2400 / 2 = 1200 m.
