Answer:

SONAR means "sound navigation and ranging"

Explanation:

In SONAR,sound waves are used to measure the depth of sea or ocean.it is based on "echo of sound".a sound wave is sent from a ship and when it hits the bottom it returns back to the ship.and that reflected sound wave is heared with the help of hydrophone.the time between the occurrence of sound wave and the reflected wave is then calculated.and with its help the depth of ocean or sea is measured.
