The amplitude is the height of the wave, 10 cm. A displacement-time graph shows how the displacement of one point on the wave varies over time. You should be able to work out the frequency of a ...

With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes ...

A loud sound has a large amplitude, a high pitched sound has a high frequency. Musicians and scientists ... and forth a lot and so the peaks on the graph are big. A quiet sound makes the air ...

And lots of pretty graphs don’t hurt either ... with Amplitude Shift Keying the amplitude is shifted between two levels, like playing a single note (frequency) on a piano loudly or softly ...

For example, in AM radio, the voltage (amplitude) of a carrier with a fixed center frequency (the station's channel) is varied (modulated) by the analog audio signal.

The biomechanical variables that determine its intensity are the frequency and amplitude. The extent of the oscillatory motion determines the amplitude (peak to peak displacement, in mm) of the ...
