"Why have environmentalists and the government joined in an alliance with the electrical industry in promoting an undeniably dangerous product? Whose side are they on anyway?"
– Walt McGinnis, "The Dark Side Of CFLs," April 2009
Energy and Light
Energy is inherent in all animate and inanimate matter. It is transient and easily gets transformed from one form to another. For example, when a light gets turned on, electrical energy gets transformed into heat energy and then into light energy. The visible light that is emitted from the bulb is a type of electromagnetic radiation within the electromagnetic spectrum. It is the total frequency range of electromagnetic radiation or light that extends from 0 Hertz (Hz) to 1023 Hertz or infinity—depending on the source.
The different types of radiation are grouped by their frequency and include in decreasing frequency: cosmic–ray photons, gamma rays, x–rays, ultraviolet radiation (UV), visible light, infrared radiation, microwaves, and radio waves. Radiation with a high frequency emit high amounts of energy and have short wavelengths. On the other end of the spectrum, radiation with low frequency have long wavelengths and emit low amounts of energy.
The radiation is comprised of oscillating waves—repeated cyclic patterns of alternating (weak) electric and (strong) magnetic fields. The
