Sound  Sound wave:- A sound is a form of energy that is produced by a vibrating object. These vibrations Continue to and give the sensation of hearing. Production of the sound and propagation of sound Sound is produced when we vibrate any object and vibrating objects disturb the particles of the medium through which sound travel. These vibrations are continued to move the particle and reach at another end. Diagram How the vibrations transferred by A tuning fork The vibrations are transferred by the tuning fork by consecutive compression and rarefaction regions. Compression It is the reason in a medium where the leg of tuning fork moves outward and creates the region of high pressure which is called the compression region. Rarefaction region it is a region in a medium where there is high density,is called rarefaction region. Mechanical waves: - The waves which required the medium to travel from one place to other place, that waves are known as Mec...
