F: Definition of Light Flashcards
as an artificial source of illumination.
as “visually evaluated radiant energy”.
A form of wave energy and therefore
has frequency and wavelength. In
comparison with other wave phenomena,
light has a higher wave frequency than
radio and radar.

orange, yellow, green, blue, indigo, violet,
is non-visible light can have both harmful and beneficial
effects.
Ultraviolet Radiation (UV)
is non-visible light characterized by its relation to heat.
