$\huge\mathfrak\green{Introduction:-}$

Sonar is a technique that uses sound propagation to navigate, communicate with or detect objects on or under the surface of the water, such as other vessels.

How it works:-

A sonar device sends pulses of sound waves down through the water. When these pulses hit objects like fish, vegetation or the bottom, they are reflected back to the surface. The sonar device measures how long it takes for the sound wave to travel down, hit an object and then bounce back up.

Uses:-

helpful for exploring and mapping the ocean because sound waves travel farther in the water than do radar and light waves.
