It is a technique that uses sound waves to map or locate objects in the surroundings...
APPLICATIONS OF SONAR:
Submarines use sonar to detect other vessels.
Sonar is also used to measure the depth of water.
Oceanographers(People who study of the physical and biological aspects of the ocean) use sonar to map the contours of the ocean floor.
It is also used for searching for oil on land. A sonar pulse is sent into the ground. Echoes come back from the different layers of soil and rock and tell geologists what kinds of soils and rocks are present. This helps them identify areas for drilling that are most likely to contain oil or gas.
