Question

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

Answer 1

Hint:A sound ranging technique is called the calculation of the distance between a source of sound waves and a considered point.As they can penetrate deep into the water without losing strength, ultrasonic waves are used for sound ranging. And their frequency lies outside audibility boundaries. One of the applications of the sound spectrum is to locate the underwater location of the object and to find the sea level.

Complete answer:
By calculating the time lapse between the origin of the sound and its arrival at the point, sound ranging is a tool for determining the distance between a point and the direction of a sound source.

Artillery sound ranging is a means of identifying the coordinates of a hostile battery in ground warfare using data obtained from the sound of the firing of its guns (or mortar or rockets). The same techniques can also be used to direct artillery fire at a position with known coordinates.

The perfect example of how a ship on the ocean uses the reflection qualities of sound waves to assess the ocean's depth is SONAR. A sound wave is emitted from the seabed and bounces off it. The distance from the ship to the bottom of the ocean can be estimated since the speed of sound is understood and the time lapse between transmitting and receiving the sound can be measured. Sonar (Sound Navigation And Ranging) is called this method.

Note: So, in short it can be said that sound ranging is the method by which it is possible to measure the distance of an object such as a wall, mountain, etc. The sound echo phenomena from an object is included here.
