The speed of propagation vw is the distance the wave travels in a given time which is one wavelength in a time of one period. Amplitude wavelength and speed Amplitude. V w l T.
The amplitude is the maximum height observed in the wave.
The amplitude is the maximum height observed in the wave. A A wave consists of alternation crests and troughs. The waves must have the same frequency and wavelength but can have different amplitudes. F v l displaystyle f frac v lambda.
