Solution

The correct option is D $\frac{t}{2}$ s
The time taken by the ultrasonic waves to go from the ship to the bottom of the sea is half that taken for the wave to go out from the ship and to return. So, required time is $\frac{t}{2}$ s.

Q. Ultrasonic waves are sent in the sea from a sonar device attached to a ship. These waves take 0.6s to travel from the ship to the bottom of the sea and back to the ship in the form of an echo. What is the depth of the sea? (Speed of sound in water = 1500m/s)

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 the velocity of wave in sea water is 1400 m $s^{- 1}$ , find the depth of sea.
