\Light\ (l[imac]t), n. [OE. light, liht, AS. le['o]ht; akin to OS. lioht, D. & G. licht, OHG. lioht, Goth. liuha[thorn], Icel. lj[=o]s, L. lux light, lucere to shine, Gr. leyko`s white, Skr. ruc to shine. [root]122. Cf. {Lucid}, {Lunar}, {Luminous}, {Lynx}.] 1. That agent, force, or action in nature by the operation of which upon the organs of sight, objects are rendered visible or luminous. Note: Light was regarded formerly as consisting of material particles, or corpuscules, sent off in all directions from luminous bodies, and traversing space, in right lines, with the known velocity of about 186,300 miles per second; but it is now generally understood to consist, not in any actual transmission of particles or substance, but in the propagation of vibrations or undulations in a subtile, elastic medium, or ether, assumed to pervade all space, and to be thus set in vibratory motion by the action of luminous bodies, as the atmosphere is by sonorous bodies. This view of the nature of light is known as the undulatory or wave theory; the other, advocated by Newton (but long since abandoned), as the corpuscular, emission, or Newtonian theory. A more recent theory makes light to consist in electrical oscillations, and is known as the electro-magnetic theory of light. 2. That which furnishes, or is a source of, light, as the sun, a star, a candle, a lighthouse, etc. Then he called for a light, and sprang in. --Acts xvi. 29.
