Using the SONAR, sound pulses are emitted at the surface of water. These pulses after being reflected from bottom of water, are detected. If the time interval from the emission to the detection of the sound pulses is 2 seconds, find the depth of the water.

Solution

Time between the transmission and detection of the pulses = 2 seconds

Speed of sound in water, v = 1450 m/s

Time taken by the pulse to travel to the bottom of water = 2/2 sec = 1 sec

Therefore, using the distance-time formula, we have

Depth of water = v $\times$ t = 1450 x 1 = 1450 m.
