SOUND
Sound. Sound is a form of energy which usually produces the sensation of hearing in our car.
Sound is produced by vibrating objects. A vibrating tuning fork produces sound. The sound of human voice is also produced due to vibration in the vocal chords.
A disturbance is a rapid back and forth notion of a rapid particle about its mean position. Vibration is also called oscillation.
Different sources of second in our environment are human beings, birds, animals, bells, machines, musical instruments like guitar, sitar, mridangam, etc.
The matter through which the sound is transmitted from the point generator to the listener is called medium. The medium can be solid, liquid, and gas.
The Disturbance set by sound in the medium travels through the vibrating of the particles of the medium. Hence, the particle of the medium is not when the same vibrating object suddenly moves backward it causes temporary low pressure region which is called rarefaction. The compression is a region of high pressure and rarefaction is a region of low pressure. Pressure is related to the number of particles of a medium in a given volume. More density of the particles in the medium quies more pressure and

Time period
Time taken by a vibrating body or a vibrating particle to complete one oscillation is time period.
