Electromagnetic waves can be described by just three components: amplitude, frequency, and wavelength. The amplitude is the same as the intensity or energy content of a wave. These can have the following extreme conditions for their absolute magnitudes. A is amplitude, n is frequency, l is wavelength. (1) A=0, n=0, l=¥; (2) A=0, n=¥, l=0; (3) A=¥, n=0, l=¥; (4) A=¥, n=¥, l=0. Although the amplitude remains independent throughout the lifetime of the wave, the product of frequency and wavelength is always a constant equal the speed of light. However, when waves interact, the interaction only affects the amplitude not the frequency or wavelength.
In the process for the wave to become real or unreal, technically means in phase or out of phase, all that is needed is to choose one out of these four conditions always with the ratio of 2 to 1, double infinity or double zero.
