sonar

Sonar, which stands for Sound Navigation and Ranging, is a technology that uses sound waves to detect and locate objects underwater. It works by sending out sound pulses, which bounce off objects like submarines or the ocean floor, and return to the source. By measuring the time it takes for the echoes to come back, sonar can determine the distance and shape of the objects. It is commonly used in marine activities such as navigation, fishing, and mapping underwater terrains, as well as in military applications to detect submarines and other vessels.

    Sonar, short for Sound Navigation and Ranging, is a technology that uses sound waves to detect objects underwater and measure distances. It works by emitting sound pulses and listening for echoes that bounce back from objects like submarines, shipwrecks, or the seafloor. By analyzing the time it takes for the sound to return, sonar can calculate how far away an object is and create images of underwater terrains. This technology is widely used in marine navigation, fish finding, and oceanographic research, helping to enhance safety and gather valuable data in aquatic environments.
