Sonar, short for Sound Navigation Ranging, is a technology that uses sound waves to detect objects underwater. It works by emitting sound pulses and analyzing the echoes that bounce back from objects, allowing for the measurement of distance and location. Sonar is commonly used in various applications such as navigation, fishing, and military operations.
