f = frequency = number of waves produced by a source per second, in hertz Hz. T = period = time it takes for one complete vibration or oscillation, in seconds s. A boat at sea bobs up and down as ...

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 ...

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 ...
