摘要

正确理解彩虹的形成机制能够让学生对大气光学现象形成正确的认知.本文设计了一种便于学生自行搭建的彩虹再现装置,并基于装置对彩虹再现的影响因素进行实验分析.分析发现:选用平行性好的光源照射均匀分布且密度较大的液滴群时,更容易观察到清晰明亮的彩虹.最后本文还对彩虹的偏振特性进行了探究.

Abstract

 A correct understanding of the formation mechanism of rainbow can help students form a correct cognition of atmospheric optical phenomena. In this paper, a rainbow reproduction device is designed for students to build by themselves, and the influencing factors of rainbow reproduction are analyzed based on the device. It is found that it is easier to observe clear and bright rainbow when the droplet group with uniform distribution and large density is irradiated by the light source with good parallelism. Finally, the polarization characteristics of rainbow are demonstrated.
