The velocity of ultrasonic sound in water is 1400 m `s^(-1)` . The depth of the ocean as detected by SONAR if the time taken to receive the reflected wave is 15 s , is `"________"`.

Write the following statements in a sequential order to find the depth of the ocean bed by the using sonar . (A) The depth of the ocean bed can be found by d = (vt)/(2) . (B) At the bottom of a ship two devices , one is transmitter which products ultrasonics and a receiver for the detection of the reflected ultrasonics from the ocean bed are fixed . (C) The velocity fo ultrasonics in ocean water is 'v' and the time taken to receive the reflected ultrasonics from the ocean bed be 'f'. (D) If the depth of ocean bed is 'd' , then v = (d + d)/(t) = (2d)/(t) .

An ultrasonic wave is sent from a ship towards the bottom of the sea. It is found that the time interval between the .transmission and reception of the wave is 1.6 seconds. What is the depth of the sea, if the velocity of sound in the seawater is 1400 ms^(-1) ? Time interval between sending and receiving of the wave, t = 1.6 s Velocity of sound in sea wave, V = 1400 ms^(-1) To find : Depth of the sea, d = ?

A ship at rest is sending ultrasonic sound waves to detect a shoal of fish. If the time gap between the signal sent from the ship and received (reflected) signal is 0.5 s, then find the distance of the shoal of fish form the ship. (Velocity of sound in water is 1400 ms^(-1) )

The speed of sound in water is 1600 m/s. A boat man hears an echo 3 s after sending an ultrasonic sound into the sea. What is the depth of the sea?

Ocean waves of time period 10 s have wave velocity 15 ms^(-1) . Find the wavelength of these waves .
