Question

What is necessary for the production and transmission of sound?
A) Medium
B) Acceleration
C) Receiver
D) None

Answer 1

Since sound is one of the form of energy and for propagation of sound , sound waves are produced in longitudinal wave design and performing compression and rarefaction in the medium particles and we are able to hear the sound easily which medium wave pattern will not develop.

Complete step-by-step solution:
Sound is a form of energy which creates a longitudinal waves pattern in which compression and rarefaction are produced. Sound is heard when some vibrations are produced. For producing the sound waves three things are required, firstly an object that creates vibration by striking it, secondly that body which vibrates on striking and last medium through which sound waves can travel because when an object strikes the vibrating body then vibrations are produced that develops sound waves which must travel through a medium, such as air or water, or any other medium made of atoms and molecules only.
In different mediums speed and intensity of sound will vary but sound cannot travel without medium that means it cannot travel through vacuum.
As we can prove experimentally that sound cannot travel through vacuum by doing a bell jar experiment, if we close an electric bell in tight container and remove all air from that container and then ring that electric bell we cannot able to hear its sound because the sound waves do not get any medium for travelling and as we open that jar sound is heard because it gets the medium now which shows that medium is required for sound propagation.
So at last we can conclude that sound cannot travel without medium so it is a necessary thing in production transmission of sound.
Receiver is required to hear the sound so it is not a necessary thing in production and transmission of sound.
When sound travels with constant speed then acceleration is not produced so it is not an important thing in production of sound.
So the correct option is A.

Note: There are two types of wave, one in which medium is required for propagation called mechanical waves and second in which medium is not necessary for propagation called non-mechanical waves or electromagnetic waves. In mechanical waves the medium propagates in different patterns and waves move from one place to another.
