Question

Answer 1

SONAR(SOund Navigation And Ranging)

Answer 2

Sound Navigation 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.

Explanation:

• Sonar can be used as an acoustic location and can measure the echo properties of "targets" in water.
• An acoustic point in the air was used before the radar was introduced. Sonar can also be used for robot navigation
• The term "sonar" also refers to devices for generating and receiving sound. The sound frequencies used in sonar systems range from very low (infrared) to extremely high (ultrasound).
