中学物理光学实验,由于光源条件的限制,常要求在暗室或在光线较暗的教室进行,才能取得较好的效果。这对广大乡镇或乡村中学来说,做到是很困难的。为此,我试将阳光引入教室作为实验光源,获得良好效果、形成的光束特别清晰,即使在日间课室里,仍能见到对比强烈、光路清楚的各种光学现象。 In the middle school physical optics experiment, due to the limitation of light source conditions, it is often required to perform in darkrooms or in dark classrooms in order to achieve better results. This is very difficult for a large number of townships or rural middle schools. For this reason, I tried to introduce sunlight into the classroom as an experimental light source. The result was good results and the beam formed was particularly clear. Even in daytime classrooms, various optical phenomena with strong contrast and clear light path can be seen.
