Draw a curve showing density or pressure varitions with respect to distance for a disturbance produced by sound.Mark the position of compressions and rarefactions of this curve.Also,define wavelength and time period.

The representation of sound by a sine wave is merely an attempt to illustrate the sinusoidal nature of the pressure-time fluctuations.
The wavelength of a wave is merely the distance that a disturbance travels along the medium in one complete wave cycle. Since a wave repeats its pattern once every wave cycle, the wavelength is sometimes referred to as the length of the repeating patterns - the length of one complete wave.
Time period: The period is the time taken for one complete cycle.
Hope this helps.
