摘要: 利用光拍法测光速的实验中主要存在3个误解.笔者结合实验教学,从光拍频波的原理、光拍频波的形成和传播以及光拍频波的接收和光路调节3个方面,对光拍法测光速实验中易产生误解的内容进行了剖析并给予澄清.

关键词: 光拍频波, 光程差, 相位差, 光电流

Abstract: There are three main misunderstandings in the experiment measuring the speed of light with light beat:1, that in the principle of light beating wave; 2. that in the production and propagation of light beating wave;3. that in receiving light beating wave and setting light path

Key words: light beating wave, path difference, phase difference, photocurrent
