Question

what is sonar and its uses​

Answer 1

Answer:

sonar --- sound navigation and ranging. .

Sonar (sound navigation ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, communicate with or detect objects on or under the surface of the water, such as other vessels.
