Two major types of light in the spectrum
WebSep 23, 2004 · Most light sources we use are of two kinds: The light is created either by heat--e.g. in the hot filament in a common flashlight--or by glowing gas, as in fluorescent lighting. Sources of the second kind give more light per unit energy, but that light is concentrated in a few preferred colors, so colored objects may appear somewhat un … WebVisible light constitutes only one of many types of electromagnetic radiation emitted from the sun and other stars.
