Light, n. Etym: [OE.light, liht, AS. leót; akin to OS. lioht, D. & G. licht, OHG. lioht, Goth. liuhap, Icel. lj, L. lux light, lucere to shine, Gr. ruc to shine. 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.

---excerpt from the Illustrated Bible Dictionary
Light - The offspring of the Divine command (Genesis 1:3). "All the more joyous emotions of the mind, all the pleasing sensations of the frame, all the happy hours of domestic intercourse were habitually described among the Hebrews under imagery derived from light" (1 Kings 11:36; Isaiah 58:8; Esther 8:16; Psalms 97:11). Light came also naturally to typify true religion and the felicity it imparts (Psalms 119:105; Isaiah 8:20; Matthew 4:16, etc.), and the glorious inheritance of the redeemed (Colossians 1:12; Revelation 21:23). God is said to dwell in light inaccessible (1 Timothy 6:16). It frequently signifies instruction (Matthew 5:16; John 5:35). In its highest sense it is applied to Christ as the "Sun of righteousness" (Malachi 4:2; Luke 2:32; John 1:7). God is styled "the Father of lights" (James 1:17). It is used of angels (2 Corinthians 11:14), and of John the Baptist, who was a "burning and a shining light" (John 5:35), and of all true disciples, who are styled "the light of the world" (Matthew 5:14).
