Sonar was first used during World War I by the British Royal Navy. It was used to detect submarines by emitting sound waves and analyzing the echoes that bounced back.
Sonar (SOund NAvigation and Ranging) is used to find objects. Sonar is used to find ships, submarines, mines, and other objects in the Navy. Sonar is used in Medicine to find unusual tumors, organs, and cells. Sonar is used in Geology to find minerals, oil, rock formationsn, and water .
The first sonar invention was called the "echo sounder" and was developed in 1913 by Lewis Fry Richardson. It was initially used to measure water depth by sending sound waves into the water and measuring the time it took for the echo to return.
Yes sonar can be used at periscope depth. Surface ships also have sonar arrays on them. They are usually used to detect submarines.

The first documented use of sonar was during World War I by the British Royal Navy to detect submarines. The technology was further developed during World War II for anti-submarine warfare.
Sonar can be used to locate large shoals of fish.
In 1915, Paul Langévin invented the first sonar type device for detecting submarines called an "echo location to detect submarines" using the piezoelectric properties of the quartz.
Sonar was used to detect and hunt submarines in WW2

sonar is a device used underwater for locating submerged objects and for submarine communication by means of sound waves.
