Light
refers to
electromagnetic radiation
of all
wavelengths. Light, within the
visible spectrum, is that light which is detectable by the
human eye. In ancient times,
humans used
fire as a
heat and light source. In modern times, humans have combined
energy,
optics,
chemical reactions, and other
physical properties to produce light for a variety of
purposes. Objects as simple as a
street light have, momentarily, been confused for an unknown
object under certain
weather related conditions. A witness should consider their
environment when
observing an unknown lighted object. The distant light of a
known object may be visible during
winter months when the normal
foliage of the area has fallen from the
trees. In
mountainous and
hilly areas,
vehicle lights, both
on-road and
off-road, may be seen for miles. |
