Question

Explain briefly how the depth of ocean is measured by the SONAR method.

Answer 1

SONAR(sound navigation ranging)

✍They send electric/sound signals which eventually hit the bottom of the ocean floor, the time it takes to reach the bottom of the ocean floor and to come back indicates how deep that part of the ocean is .An apparatus called sonar is used to locate underwater objects and to find the depth of water.it sends out high frequency sound vibrations called ultrasonic vibrations,into the water.the time taken by the vibrations to return is then used to calculate the distance of the reflecting surface.
