以可见光（非X射线）作入射光，观察康普顿效应。利用荧光光度计，将波长400-550nm的可见光，通过一定物质散射后，观察与入射线方向相垂直的散射线及其相对强度。以可见光作为入射线同样可以观察到康普顿效应，即观察到波长大于或等于入射线波长的散射线。除此，还出现了逆康普顿效应，即观察到波长小于入射线波长的散射线。以上两种情况尚未见诸报道。通过该实验设计，在一般实验室可以较为方便地验证康普顿效应和逆康普顿效应。如果使用波长更大或更小的电磁波作为入射电磁波，来观察它们的散射电磁波及其相对强度，将有助于电磁波最大波长最小波长等问题的深入研究。%Objective Observe Compton effect with visible ray. Method With fluorescent spectrophotometer, when visible ray (λ:400-550nm) as incident ray passing through the substance, detect the scattered rays which direction is perpendicular to that of the incident ray. Results Using visible ray, we also observe Compton effect and inverse Compton effect, these phenomena differing from traditional Compton effect haven’t been reported yet. Conclusion In general laboratory, using visible ray, can observe Compton effect and inverse Compton effect easily. When we will have tested with all sorts of incident rays which wavelength are more and more short (and also more and more long), it will be help to the problem about the shortest and longest electromagnetic wavelength.
