Answer (2)
Sonar uses sound waves to detect and locate objects underwater by emitting sound waves and measuring how long it takes for them to return. This technology allows ships to find fish and measure water depth effectively. By understanding the speed of sound in water, sonar systems can accurately calculate distances to objects beneath the surface. ;
Sonar uses sound waves to detect underwater objects by emitting these waves and measuring the time they take to bounce back. The technology calculates distance based on the speed of sound in water, which is about 1,500 meters per second. Sonar is utilized in fishing and ocean exploration for effective navigation and research.
