Frequency - Amplitude

    Do higher frquencies have higher amplitude? Bats communicate at Ultasonic frequencies. DOes this mean the waves amplitude is very high?

    The amlitude of sound waves is independent of
    their frequency. The amplitude determines
    the strenght (volume) of the waves.

    Live long and prosper.

    For example, in an explosion, it produces a very loud bang. (ie large amplitude) The dull sound it produces indicates the sound wave has low frequency(pitch).

    We can characterize a sine wave

    completely with three quantities, frequency, amplitude and phase. They can be specified separately.

    frequency is 1/peroid
    that mean how must the peroid in 1 second is the frequency
    so the large frequency doesn't mean large amplitude
