, Sound
Sound is a form of energy which creates a sensation of hearing
when it reaches the ear.
Law of conservation of energy is also applicable to sound.
Sound is produced by vibrating objects.
For example: Striking a tuning fork, Vibrating vocal cords (human voice)
Vibration : is a rapid back-and-forth motion of an object.
, How Sound is Produced?
The substance through which sound travels is called a medium. A
medium can be a solid, liquid, or gas.
Process of Sound Propagation:
Note: It is the disturbance caused by the vibrations that travels through the medium,
not the particles themselves.
