An instrument utilized for measurement the depth of oceans

Reference no: EM13671781

An instrument utilized for measurement the depth of oceans sends ultrasonic signals to the bottom of the ocean. The signal is received in 0.75 sec after the reflection from the bottom of the ocean. The freq of the signal is 60 KHz and the velocity of the ultrasonic signals in seawater is 1450m/s. Discover the depth of the ocean at the location of the experiment.
