    Following are the main characteristics of sound wave:

    • Wavelength: Wave length is the length between two consecutive peaks, i.e. crest or two consecutive valleys, i.e. trough of a wave. Wave length is represented by Greek letter λ (lambda).
    • Amplitude : Magnitude of maximum disturbance on either side of the normal position or mean value in a medium is called amplitude.
    • Time period : Time required to produce one complete wave is called time period or time taken to complete on oscillation is called the time period of the sound wave.
    • Frequency: The number of sound waves produced in unit time is called the frequency of sound waves. For example, if a source of sound produces 20 sound waves in one second then the frequency is 20 Hz.
