仔细分析分光镜实验得到的光谱,七种单色光呈细带状分布,即波长不是一个确定的值,而是一个范围.实验与理论分析表明,实际的单色光即单一频率的光是不存在的,而是由在波长λ0 附近,在Δλ宽的范围内,由许多不同波长的光按一定的强度分布组合而成的.实际物体发光时,发光原子在做 The spectra obtained from the spectroscopic experiments were carefully analyzed. The seven monochromatic lights were distributed in a fine band, ie, the wavelength was not a definite value but a range. Experimental and theoretical analysis showed that the actual monochromatic light is a single frequency light. It does not exist, but is formed by a combination of certain intensity distributions of light of many different wavelengths within a wide range of Δλ in the vicinity of the wavelength λ0. When the actual object emits light, the luminescent atoms do
