Explain the working and application of a sonar.




SONAR stands for SO und N avigation A nd R anging.


Working of SONAR

SONAR has two components

  1. A transmitter- for transmitting ultrasonic waves
  2. A detector- for detecting the reflected ultrasonic waves

Sonar is installed in a boat or a ship.

  • The transmitter 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 later interpreted.


Applications of SONAR

  1. It is used to find depth of sea
  2. It is also used to locate underwater hills, valley, submarines etc
