Quest: What are wavelength, frequency, time period and amplitude of a sound wave?

a) Wavelength: The distance between two consecutive compressions or two consecutive rarefactions is known as the wavelength. Its SI unit is metre (m).
(b) Frequency: The number of complete oscillations per second is known as the frequency of a sound wave. It is measured in hertz (Hz).
(c) Amplitude: The maximum height reached by the crest or trough of a sound wave is called its amplitude.
