摘要
探索牛顿环能否测量单色光的波长,首先用已知波长的钠黄光照射牛顿环,形成干涉图样,测量第m,n级的直径,然后用三种不同颜色的LED单色光作为光源,测量出相同级次时的直径大小,通过对比计算出三种颜色LED单色光的波长。
Exploration of Newton's rings can measure the wavelength of monochromatic light,the first known wavelength with sodium yellow light exposure Newton ring,an interference pattern is formed,measurement m,n diameter of the order,then with three different colors of monochromatic LED as a light source,measure the diameter of the same size class times,and calculated by comparing the three color LED monochromatic wavelength.
