Maxwell's
electromagnetic theory of light would be described as a vibration of
light orthogonal electric and magnetic fields, this theory seems to have
been around in 1900, fairly complete, but the electromagnetic theory
can not explain all experimental phenomena, which led to Planck,
Einstein The use E = hν to describe the smallest unit of energy produced
the light quantum hypothesis. Subsequent experiments show that the
photon also has momentum, is an elementary particle: photon concept was
born, creating a human for the quantized electromagnetic field more
in-depth study. |
