  • What Is the Difference Between Amplitude and Frequency

    The difference between frequency and amplitude is that frequency is a measurement of cycles per second, and amplitude is a measurement of how large a wave is. Amplitude represents the wave's energy. Waves are defined as energy transferred from one place to another. The way in which the energy travels is called the medium.

  • What are frequency, amplitude, and phase waves? Quora

    I think you are talking about modulation methods, not waves. Amplitude modulation is fairly self explanatory: a large value is represented by a large amplitude of the carrier wave, and a small value, by a small amplitude. With frequency modulation

  • Do low frequency sounds with high amplitude damage
