Sonar is an artificial form of echolocation, which involves the use of sound navigation and ranging techniques for the propagation of sound underwater. This technology is used for navigating, communicating or detecting objects that are under or above the water surface. Specialized sea creatures such as whales and dolphins have the ability to use sound reflected from waves for sensing and locating distant objects or prey, this is called echolocation. Bats also use the same technique to navigate in the dark. Humans also use echolocation through sonar technology in ships and submarines to avoid icebergs, locate ...
