SONAR means Sound Navigation And Ranging is a technique that uses sound propagation to navigate, communicate with or detect objects on or under the surface of the water, such as other vessels.

Additional Information :-

  • The depth of an ocean, a strong ultrasonic wave is sent from the ship towards the bottom of the ocean.

  • This ultrasonic wave is received back after it is reflected from the bottom of the sea.

  • The time interval t for travel of sound waves from the source to the receiver after reflection is noted.

  • The distance travelled by the ultrasound ray is given by the equation: 2d=vt, where v is the velocity of sound.
