摘要

对于光波长的电磁波进入透明介质后的透射和折射现象，标准的解释是电磁波的速度发生了变化。然而，无需假设电磁波的速度发生了变化，这些现象也是可以解释的。在各种介质中，实际速度并不会发生变化，但人们习惯性地假定速度会发生变化，因为这有利于进行简单的计算，并能做出易于理解的解释。本文介绍了在单个原子水平上透射和折射的基本原理，其中电磁波的速度保持不变。

Optical transmission and refraction at the atomic level

The standard explanations for the phenomena of transmission and refraction of electromagnetic waves of optical wavelengths upon entering a transparent medium is in terms of the speed of the waves being altered. However, these phenomena are explicable without assuming that the speed of electromagnetic waves changes. The actual speed does not alter in various media but is customarily assumed to do so as this facilitates straight-forward calculations and allows easily understood explanations to be advanced. An underlying account of transmission and refraction at the level of individual atoms is presented in which the speed of electromagnetic waves remains constant.

期刊介绍： Physics Education seeks to serve the physics teaching community and we welcome contributions from teachers. We seek to support the teaching of physics to students aged 11 up to introductory undergraduate level. We aim to provide professional development and support for teachers of physics around the world by providing: a forum for practising teachers to make an active contribution to the physics teaching community; knowledge updates in physics, educational research and relevant wider curriculum developments; and strategies for teaching and classroom management that will engage and motivate students.
