时间和频率是逆相关的，即：时间单位越小(或光波振荡越快)频率数量越大。
Time and frequency are inversely related; that is, smaller units of time (or faster oscillations of light waves) result in larger frequency Numbers.
关键是发现蓝色光波的振荡频率远高于红色光波，黄色和绿色光波的振荡频率介于两者之间。
The essential point is that the blue waves oscillate much faster than the red waves, and the yellow and green waves are somewhere in between.
由吸收光谱确定泵浦光波长，由荧光光谱确定激光振荡波长。
The pumping light wave and the laser oscillation wave are determined by the ultraviolet-visible absorption spectra and fluorescence spectra, respectively.
