प्रश्न
Draw a curve showing density or pressure variations with respect to distance for a disturbance produced by sound. Mark the position of compression and rarefaction on this curve. Also, define wavelengths and time periods using this curve.

उत्तर
The points of maximum density (or pressure) and minimum density (or pressure) are also called crests and troughs respectively.
Wavelength (A): The distance between two consecutive compressions or two consecutive rarefactions is called wavelength.
Time period (T): Time period of a wave is defined as the time taken by its two consecutive compressions or rarefactions to cross a fixed point.
