the bending of light
||Refracted light is
light that bends as it travels from one substance to another.|
The amount of refraction that occurs depends upon the density of the
substance and the angle at which the light is entering the substance.

The refraction of sunlight (or moonlight)
by ice crystals can result in a
number of beautiful optical effects like
which are produced when sunlight or moonlight is refracted
by the pencil-shaped ice crystals of
Light refraction is also responsible for other unique effects, like
bending the rays of a setting sun to give it
an elliptical, "flattened-out" appearance.
