…In 1900, PEA Lenard discovered that this phenomenon is due to electrons being emitted from metals when exposed to ultraviolet light. Around the same time, JPLJ Elster and Hans Friedrich Geitel (1855-1923) discovered that the number of photoelectrons emitted from metals per unit time is proportional to the intensity of the incident light. In 1902, Lenard further clarified the important fact that the maximum energy of a photoelectron does not depend on the intensity of the incident light, but only on the wavelength of the light. … *Some of the terminology that mentions "Elster, JPLJ" is listed below.

…この現象は,1900年にP.E.A.レーナルトによって,紫外光照射により金属から電子が飛び出すためであることが明らかにされた。また同じころにJ.P.L.J.エルスターとガイテルHans Friedrich Geitel(1855‐1923)は,金属から飛び出す光電子の単位時間当りの数は,入射光の強度に比例することを見いだした。さらに02年にレーナルトは,光電子がもつ最大エネルギーは,入射光の強度にはよらず,入射光の波長にのみ依存するという重要な事実を明らかにした。… ※「エルスター,J.P.L.J.」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 |
