How are the frequency and amplitude of a wave related?
They are fundamentally related in that one cannot exist without the other. FREQUENCY In a general context, frequency is the number of cycles per second. It could refer to an oscillating pendulum, tidal waves, audio or radio signals. Whatever the frequency, medium or shape, it cannot exist without at least two amplitude levels. A square wave would be an example of this. Triangular and sine waves would could cycle through an almost infinate range of values. A frequency does NOT have to be AC. Think Digital Square Wave computer clock. AMPLITUDE For a frequency to to exist there must be some change in value over the cycle. Consider an electrical frequency. For the usual Sine Wave the +peak would be as positive above 0v or ground, as the -peak would be as negative relative to the 0v or Ground. The values of either of these peaks, would be considered the amplitude of the wave. Here Vp = Vp-p / 2 Seeing the wave as a graph, or scope display, the Horizontal scale INDIRECTLY gives the Frequency
