wavelength: the minimum distance after which the state of disturbance is repeated in wave motion is called wavelength of the wave.
time period: The time taken to complete one oscillation of the density of the medium is called the time period of the sound wave.
frequency: The number of oscillations of the density of the medium at a place per unit time is called the frequency of the sound wave
