Answer 2

Answer:

It is a device that uses ultrasonic waves to measure the distance , direction and speed of underwater objects. The transmitter produces and transmits ultrasonic waves. These waves travel through water and after striking the object on the seabed, get reflected back and are sensed by the detector. The detector converts the ultrasonic waves into electrical signals which are appropriately interpreted.Application of SONAR:-• Detecting & tracking submarines, ships, etc. • Mapping the ocean floor. • Detecting under-water mines.Hope it helps you
