In physics, the amplitude of a wave is a measure of the maximum displacement or distance moved by the wave from its equilibrium position. The frequency, on the other hand, is the number of complete oscillations or cycles that a wave undergoes in a given unit of time, typically measured in Hertz (Hz). The amplitude of a wave does not directly affect its frequency. These are two distinct properties of a wave. Amplitude is related to the energy of the wave, with larger amplitudes corresponding to more energy. Frequency is related to the pitch of the wave, with higher frequencies corresponding to higher pitches. However, in certain conditions, such as in a nonlinear medium or under specific circumstances like wave shoaling or the presence of a strong sound source, the amplitude can have an indirect effect on the wave's speed, which can in turn affect the frequency if the medium's properties change in a way that alters the speed of wave propagation. But this is not a direct relationship between amplitude and frequency. To summarize, in general: - Amplitude is the measure of the wave's displacement from its equilibrium position. - Frequency is the number of oscillations per unit time. - The amplitude of a wave does not directly affect its frequency. read more >>

No real wave is perfectly linear. A very large amplitude can increase the speed of sound in a medium. ... The frequency of sound can affect the perceived loudness, where amplitude is held constant. Also, the amplitude can affect one's sensitivity to detecting small changes in pitch.read more >>
