Explain the working and application of sonar?
Answers
Answer:
Sonar 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 through a detector.Sonar (sound navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, communicate with or detect objects on or under the surface of the water, such as other vessels.
Working of SONAR :
It consists of a transmitter and a detector and is inst.alled in a ship or a boat.
The transmitter in SONAR produces and transmits powerful ultrasonic waves.
Applications of SONAR Technology :
Special sonars are used in ships and submarines for underwater communications.
Medical imaging for the detection of cysts and cancer cells are done using sonar and this method is known as sonogram.
