The resulting electron radiation is released in bundles of light energy which travel at a speed of 299 792 458 m / s, equivalent to the speed of light, as quantized harmonic waves. This electromagnetic waves are grouped according to their wavelength and the this results in the electromagnetic spectrum. The resultant magnetic and electric waves move perpendicularly to each other having certain characteristics which are Amplitude, frequency and wavelength.
The movement of the electromagnetic waves is in form of patterns. The distance that exists between two peaks is the wavelength of the wave. The wavelength of a waveform is measured in meters. This is illustrated in the figure below.
Frequency can be defined as the number of oscillations of the wave per unit time. The frequency of waves is not constant, it varies and the variation greatly depends on the type and nature of the electromagnetic radiation. The frequency of a wave is measured in Hertz. The wave can have high frequency or low frequency as indicated in the diagram below.
This is the process in which two waves superposes to form one resultant wave. For interference to occur, the source of the waves must be coherent. If two electromagnetic waves having the same frequency get together i.e. they superpose, it results into a wave which has the resultant magnetic and electric field strength equal to the sum of fields of the two waves. When two strong waves moving that have their fields moving in one direction, i.e. same direction in time and space, the resulting waveform is twice that of each individual waveform (Encyclopædia Britannica Online). This results in constructive interference. However, the superposition of a wave having an electric field in one direction in space and with another electromagnetic radiation wave which has the same frequency but with
