人教版高中物理选修3-5教材中氢原子光谱一节有这样的描述:“各种原子的发射光谱都是线状谱,说明原子只发出几种特定频率的光。”如果原子只能发出几种特定频率的光,根据玻尔的能级理论,原子光谱的谱线没有宽度的绝对细线。事实上,即使最精密的光谱仪,所拍摄的谱线仍有一定宽度, People’s Education Edition High School physics elective 3-5 textbook hydrogen atom spectrum section is described as: “The emission spectra of various atoms are linear spectrum, indicating that the atom emits only a few specific frequencies of light.” If the atom Only a few specific frequencies of light can be emitted. According to Bohr’s theory of energy level, there are no absolute thin lines in the spectral line of the atomic spectrum. In fact, even the most sophisticated spectrometer, the spectral line shot there is still a certain width,
