Question

Explain the working and application of a sonar?

Answer 1

SONAR stands for SOund Navigation And Ranging. it is a device installed in ships and submarines. it uses ultrasonic waves to measure the distance, direction and velocity of an underwater object. it has a transmitter and a detector. the transmitter transmits the wave and after striking the object, it gets reflected back and is sensed by the detector. the detector then converts it into electrical signals which are appropriately interpreted.

Sonar is simply making use of an echo. When an animal or machine makes a noise, it sends sound waves into the environment around it. Those waves bounce off nearby objects, and some of them reflect back to the object that made the noise.
