On sending an ultrasonic wave from a ship towards the bottom of a sea, the time interval between sending the wave and receiving it back is found to be $1.5 s$ . If velocity of wave in sea water is $1400 m s^{- 1}$ , find the depth of sea.

Solution

We know,
$2 d = v \times t; d = ? v = 1400 m / s t = 1.5 s$
Then,
$2 \times d = 1400 \times 1.5$
$⟹ d = 1050 m$
