sonar waves

Sonar waves are sound waves used to detect and locate objects underwater. The term "sonar" stands for Sound Navigation and Ranging. By sending out sound pulses and listening for their echoes, sonar systems can measure distances and identify shapes, helping in navigation, surveying the ocean floor, or finding submarines and schools of fish. There are two main types: active sonar, which emits sound waves, and passive sonar, which listens for sounds made by objects in the water. This technology is vital in marine exploration, fishing industries, and naval operations.
