On earth, our major source of radiant energy is the sun. It supplies warmth (heat or infrared radiation), light radiation (both visible light and ultraviolet light), and a wide range of energy of other types (e.g., X-rays, gamma rays, and cosmic rays). These energy forms, as well as radio, television, and radar waves, are closely related manifestations of the same phenomenon, electromagnetic radiation. The energy forms differ only in their wavelength (the distance from peak to peak of the wave pattern), which may range from kilometers (thousands of meters) to less than a nanometer (one billionth of a meter).
