An electromagnetic wave consists of two waves at perpendicular planes, on representing the electrical field while the other represents the magnetic field. This spectrum is split up into about 81 octaves, much like the octaves of sound, which scientists have categorized in order to depict the usefulness of the different properties. Theoretically electromagnetic waves can be as long as the expansive width of the universe in one wave, to a wavelength the size of a quanta (the smallest amount of energy that can be transmitted). That, however, is at this point in time negligible because we either cannot detect wavelengths so extremely large or infinitesimally small. So generally the spectrum is regarded to be set between 30,000,000 km and .0001 angstroms (1 km is equal to 1 X 10^13 angstroms). The longe... |
