Light is the part of the electromagnetic radiation that can be perceived by the human eye.
In physics, the term light is used in a broader sense and includes all of the radiation field known as electromagnetic spectrum visible, visible light while expression specifically notes radiation in the visible spectrum.
Like all electromagnetic radiation is composed of elementary particles devoid of mass called photons.
The light has a complex nature: it depends on how we observe will manifest as a wave or as a particle.
These two states are not mutually exclusive , but are complementary (see wave-particle duality).
BUT, however , to obtain a clear and concise study of nature , we can classify the different phenomena in which it participates by theoretical interpretation.
