|
|
the phenomenon of electrons being emitted from a metal when struck by incident electromagnetic radiation. explanation of
the photoelectric effect was one of the first triumphs of quantum mechanics. in his famous paper of 1905,
einstein extended planck's quantum hypothesis by postulating that quantization was not
a property of the emission mechanism,[link widoczny dla zalogowanych], but rather an intrinsic property of the electromagnetic field. using this
hypothesis, einstein was able to explain the observed phenomenon that the maximum kinetic energy
k of emitted electrons varied with frequency of incident radiation as
