- n light That which makes things visible; in physics, that form of energy which, acting upon the organs of sight, renders visible the objects from which it proceeds. The now abandoned emission or corpuscular theory, which was advocated by Newton, represented light as consisting of minute material particles emitted by the luminous body and traveling through space in all directions from it, with immense velocity; the sensation of sight being due to the action of these particles upon the eye. According to the undulatory theory, which is now generally accepted, light is a kind of undulatory motion produced by the luminous body in the particles of an elastic, imponderable medium called the luminiferous ether (see ether, 2), which is supposed to fill all space, as also the interstices of all bodies. This motion is propagated in waves (see wave) in all directions from the luminous body, and with a velocity in a vacuum of about 186,000 miles per second. The rays sent out or radiated in straight lines from the luminous body differ in wave-length, although apparently propagated with the same velocity; the eye is sensitive to those only whose wave-lengths are included between certain narrow limits, namely, those corresponding to red and violet light (see spectrum). Light is, then, a part of the kind of energy called radiant energy (see radiant energy, under energy, and radiation). The electromagnetic theory of light, proposed by Maxwell, supposes light (or, more generally, radiant energy) to be an electromagnetic disturbance propagated by vibrations at right angles to the direction of the ray, and taking place in the same ether the strains or vibrations of which serve to propagate electromagnetic induction. In confirmation of this theory, it is found that the experimentally determined velocities of the propagation of light and of electromagnetic induction are nearly the same. The principal phenomena of light are grouped under the following heads: Absorption, or the transformation of the vibration of the ether into the molecular vibrations of the body upon which the light falls or through which it passes. The effect of the absorption of part of the light-rays by a body is to give it color; thus, grass is green because it sends back to the eye only the rays which together produce the effect of green, the other rays being absorbed; and a piece of red glass owes its color to the fact that it transmits only that part of the light whose combined effect upon the eye is that of red. According to the degree of absorption of light, a body is said to be transparent, translucent, opaque, etc. Connected with absorption are the phenomena of fluorescence and phosphorescence.
