Question

explain the working of sonar​

Answer 1

Answer:

working of sonar:

The transmitter in SONAR produces and transmits

powerful ultrasonic waves. the ultrasonic waves travel through the water and after striking the target the beam is reflected from the seabed and is recieved by an under water detector.

What is Sonar?

SONAR stands for Sound Navigation And Ranging . Sonar is a device that uses ultrasonic waves to measure the distance , direction and speed of underwater objects

Working

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. The distance of the object that reflected the sound wave can be calculated by knowing the speed of sound in water and the time interval between transmission and reception of the ultrasound. Let the time interval between transmission and reception of ultrasound signal be t and the speed of sound through seawater be v. The total distance, 2d travelled by the ultrasound is then, 2d = ux t.
