Question

What is meant by sound ranging ? Give one use of sound ranging.

Answer 1

Sound ranging is a method for determining the distance between a point and the position of a sound source by measuring the time lapse between the origin of the sound and its arrival at the point.
SONAR is the best example that illustrates how a ship on the ocean utilizes the reflecting properties of sound waves to determine the depth of the ocean. A sound wave is transmitted and bounces off the seabed. Because the speed of sound is known and the time lapse between sending and receiving the sound can be measured, the distance from the ship to the bottom of the ocean can be determined. This technique is called sonar (SOund Navigation And Ranging).
