When electromagnetic radiation is spread out according to its wavelength, the result is a spectrum, as seen in Fig. 1. The visible spectrum, as seen in a rainbow, is only a small part of the whole electromagnetic spectrum. The electromagnetic spectrum is divided into five major types of radiation. As shown in Fig. 1, these include
