What is the name of the device which is used to find the depth of sea (or ocean) by using ultrasonic sound waves?

It takes 2.4 s to record the echo of a sonar. If the speed in water is 1450 m//s , find the depth of the ocean floor.

  • 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) .

  • Arrange the following steps in sequential order to find the depth of the ocean bed using Sonar. (A) The time taken (t) to receive the sound is measured. (B) Ultrasonic sound is sent to the ocean bed whose depth (d) is to be found from the transmitter attached to the ship. (C) If 'v' is the velocity of sound in water, the depth can be found using, v = 2d/t. (D) The ultrasonic sound reflected form the ocean bed is received by a suitable detector in the ship.

    A sonar device fixed to the ship is used to find the depth of the ocean. The ultrasonic sound produced gets reflected from the ocean bed and the time taken for the reflected sound to reach the sonar is 4 s, then write the following steps in sequence to find the depth of the ocean bed (d). (Speed of sound in ocean water is 1500 m s^(-1) ) (A) Use the formula, speed = ("distance travelled by the sound (2d)")/("Total time taken (t)") (B ) The distance travelled by the sound is equal to twice the depth of the ocean bed (d). (C )Note the total time (1) taken by the reflected sound to reach the sonar from ocean bed from given data. (D ) Substitute the values in the given formula, and find the value of 'd'.

    If the same time taken for the reflected sound to reach the sonar os 2 s, the depth of the sea is _______ m. (velocity of sound in water is 1500 ms^(-1) )

    If the time taken for the reflected sound to reach the sonar is 2 s, the depth of the sea is m . (velocity of sound in water is 1500 m s^(-1) )

    A metal rope of density 6000 kg//m^(3) has a breaking stress 9.8xx10^(8)N//m^(2) . This rope is used to measure the depth of the sea. Then the depth of the sea that can be measured without breaking is
