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.
