A SONAR device on a submarine sends out a signal and receives its echoe 3s later.If the speed of sound waves in sea water is 1530ms^-1.Find the depth of the seabed below the submarine

Open in App

Solution

Let the depth be d.
velocity of sound in water, v = 1530 m/s
Time taken in travelling 2d distance = 3 s
âˆµ Distance = velocity × time
2d = vt
2d = 1530×3
∴ d = 4590/2 = 2295 m

Two submarines are approaching each other in a calm sea. The first submarine travels at a speed of 36 km $h^{- 1}$ and the other at 54 km $h^{- 1}$ ' relative to the water. The first submarine sends a sound signal (sound waves in water are also called sonar) at a frequency of 2000 Hz. (a) At what frequency is this signal received by the second submarine ? (b) The signal is reflected from the second submarine. At what frequency is this signal received by the first submarine. Take the speed of the sound wave in water to be $1500 m s^{- 1}$
