测定玻璃折射率是新课改鲁科版(选修3-4)中一个探究实验,实验的目的在于应用折射定律来测定玻璃的折射率,以此让学生加深对折射定律的理解.此实验是学生学习光学知识的基础,实验的关键是确定光路,所以,要提高实验效果就必须先确定好光路. The determination of the refractive index of glass is an inquiry experiment in the Luke edition of the new curriculum (Electives 3-4). The purpose of the experiment is to use the law of refraction to determine the refractive index of the glass, so that students can deepen their understanding of the law of refraction. This experiment is Students learn the basics of optical knowledge. The key to experiment is to determine the light path. Therefore, to improve the experimental results, we must first determine the light path.
