    Intensity of sound waves
    Could some one please tell me the relation between the intensity of a sound wave and its frequency and amplitude?

    Sound waves are longitudinal waves. In sound, the amplitude is the volume; and the frequency determines the pitch.

    Intensity would be a better word used for light- which is a transverse wave. In light the frequency determines the color, and in light the amplitude is the intensity. But not the same in sound.

    Also:
    For a sound or light wave as the wavelenth increases, the frequency decreases at a decreasing rate.
