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.
