Explanation:
Sonar is based on the principle of reflection of sound wave (echo). It is used to measure the depth of sea.
SONAR is a technique that uses sound waves to map or locate objects in the surrounding environment. The premise is quite simple: first, emit a cluster of sound waves in the direction of an object. While a few waves will bounce off it, the remaining waves will be reflected back in the direction of the emitter.
If you were to insert one end of a tube into an enormous sea and put an ear to the other, you would definitely look like a loon. However, you would also hear the faint groaning of ships and the singing of various animals far away in the vast depths of the ocean. Leonardo Da Vinci was the first person to perform this ingenious experiment (without the fear of being judged) and discovered this whimsical phenomenon. He had successfully implemented what we now call SONAR.
