Question

Using Sonar sound pulses are emitted at the surface the pulses after being reflected from the bottom are detected if the time interval from the emission to the detection of the sound pulses is 2 second find the depth of the water take velocity of sound through water velocity is equal to 1500 M per second

Answer 1

In 2s, the sound wave goes the bottom and went back again, hence it travels twice the distance.

Hence,

Time taken to reach the bottom = 2/2s = 1second

Speed of wave = 1531m/s

Distance = Speed*Time = 1531*1

Answer 2

Hii!!!

V=2d/t

1500=2d/2

D=1500m is the req ans

Therefore the depth is 1500 m.

Hope it helps u
