Light \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

            And God made two great lights; the greater light to
            rule the day, and the lesser light to rule the

   3. The time during which the light of the sun is visible;
      day; especially, the dawn of day.

   4. The brightness of the eye or eyes.

            last, bended their light on me.       --Shak.

   5. The medium through which light is admitted, as a window,
