费涅耳双棱镜测光波波长是个典型的重要实验,它不仅使学生对光的干涉现象获得感性认识,了解光波波长的测量方法;而且,可以获得对如何实现干涉进行必要的动手能力的锻炼。在这一实验中,等高共轴的调整是首先必须满足的,这一步骤的实现也是几何光学近轴成象所必须满足的条件;狭缝与棱脊的严格平行是获得清晰干涉条纹的必要条件。因而,这个实验将对培养学生的光学实验能力起到积极的作用,但如何进行本实验的调节,许多实验
The wavelength of Fresnel prismatic light waves is a typical important experiment. It not only enables students to gain perceptual knowledge about the interference phenomenon of light, but also understands the measurement method of the wavelength of light waves; moreover, it can obtain the necessary hands-on exercise for how to achieve interference. . In this experiment, the adjustment of the concentric height is the first to be satisfied. The realization of this step is also the condition that must be satisfied for the geometrical and optical paraxial imaging; the strict parallel between the slit and the ridge is to obtain a clear interference fringe. Necessary conditions. Therefore, this experiment will play an active role in cultivating students’ optical experimentation ability, but how to carry out the adjustment of this experiment, many experiments
