黑體輻射與普朗克光量子假說    十九世紀末，黑體輻射的問題困擾了很多科學家，紛紛提出很多理論 與假設來解釋，但總是不盡理想。1900年底，普朗克(Planck, 1858~1947)用了一個能量不連續的簡諧振子假設，依照波茲曼的統計 方法，提出了黑體輻射公式。 -34 J.s。  1900年12月14日，普朗克假設：E = hf， h = 6.6260754×10 普朗克的假說具有劃時代的意義，為物理學開啟了新的紀元。但當時， 在最初五年之內，沒有人對這個假說有信心，就連普朗克本人也不太 相信，一直企圖想回到過去，用連續來代替不連續。 1905年，愛因斯坦在他的《關於光的產生和轉化的一個試探性觀點》 論文中，發展了普朗克的量子假說，大膽提出了光量子概念和光電方 程式，解釋了光電效應的現象。 1918年，諾貝爾物理學獎頒給普朗克。 1921年，諾貝爾物理學獎頒給愛因斯坦。 1923年，諾貝爾物理學獎頒給密立根。 Max Planck (1858–1947) 光電效應的歷史發展       1887 赫茲(Hertz,1857~1894)在研究電磁場波動性質時無意 中發現光電效應的現象。 1899 J.J.湯木生(J.J.Thomson,1856~1940)測量光電流的荷質 比，肯定光電流和陰極射線同樣都是高速運動的電子。 1900 雷納 (Lenard,1862~1947)，研究光電效應，發現改變 光的強度對截止電壓沒有影響，1902 提出觸發假說。 1900年12月14日，普朗克(Planck, 1858~1947)用了一個能量 不連續的簡諧振子假設，E = hf，解釋了黑體輻射結果。 1905 愛因斯坦(Einstein,1879~1955)提出光量子理論和光電 方程。在密立根實驗證實他的光電方程後，光量子理論才 開始被人們接受。(註：光子一詞是1926年由路易斯(Lewis) 提出的) 1904~1916 密立根(Millikan,1868~1953)歷經了十多年，終 於在1916年發表實驗證實愛因斯坦的光量子理論和光電方 程，並由此測得普朗克常數。 數據：Problem.
