...Einstein gave photoluminescence and the photoelectric effect as examples of the transformation of light, and showed that Stokes' law for the former and Lenard's law for the latter can be understood directly from the perspective of light quanta. However, it was not until 1916 that Einstein's formula for the photoelectric effect, which states that the maximum energy of electrons flying out of a metal plate is h ν - P ( P is the energy used by the electron to escape from the metal), was verified by RA Millikan. Also, it was not until 1923 that the Compton effect demonstrated that light actually collides with electrons as a packet of energy and momentum. ... *Some of the terminology explanations that mention "Einstein's formula" are listed below.

…アインシュタインは,光の変換の例として光ルミネセンスと光電効果をあげ,前者に対するストークスの法則と後者に対するレーナルトの法則が光量子の観点から直截的に理解されることを示した。しかし,光電効果において金属板から飛び出してくる電子のエネルギーの最大値をhν-Pとしたアインシュタインの公式(Pは電子が金属から脱出するのに使うエネルギー)が実証されたのは16年であり,R.A.ミリカンによる。また光が実際にエネルギーと運動量のかたまりとして電子と衝突することがコンプトン効果により実証されるのは23年になってからである。… ※「アインシュタインの公式」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
