摘要
采用三棱镜和光栅测量绿光波长,结果表明三棱镜测量光波波长的精确度比光栅测光波精确度更大,为实验提供了一种更精确测量光波波长的方法。
Green light wavelength was measured by the prism and the optical grating. The results was showed that the accuracy of the green wavelength which was measured by the prism was larger than which was measured by optical grating. The more accurate method of measuring wavelength was provided for the experiment
