Sine waves. Conceptual image of overlapping sine waves on a monitor. The level of current produced by an AC (alternating current) electricity generator is an example of a quantity that changes in a sine wave pattern. Fourier's theorem states that any periodic waveform (for example,the variation in air pressure due to sound waves) can be represented as a combination of sine waves | |
