课程介绍
This course takes up directly from where University Physics 1 left off: with the realization that light is an electromagnetic wave. From this starting point, we will follow a path through the following topics: • Physics of oscillation (harmonic motion) 震动 • Oscillating charges make electromagnetic waves (radiation) 电磁辐射 • Physics of waves (including sound) 波 • Light as a wave (physical optics) 光学 • Light as a particle, particles as waves (quantum physics) 量子物理 • Entropy sets limits on the possible (statistical and thermal physics) 统计物理与热力学 • The speed of light is constant (special relativity) 狭义相对论相

教学方法
At the core of this course are the videos, which have been designed to approximate as much as possible the experience of standing with me at a blackboard and figuring things out together.
视频是课程的核心内容，我们的目标是尽可能让学生觉得和教师一起站在黑板旁边，分析事情的来龙去脉。
It is extremely important that you take an active approach to watching the videos. Have a pen in your hand and paper in front of you, and work along with me.
观看视频时主动参与是非常重要的。请准备一支笔和一张纸，跟我一起进行推导。
It is also extremely important to ask questions as soon as you encounter something you don’t understand. There are sure to be things I don’t explain clearly in the videos, so don’t be afraid to let me know if you are struggling with certain concepts. Asking questions will be possible through the online forum.
遇到不明白的问题及时提问也是很重要的。在视频中我不可能将所有的内容都解释一遍，所以你不必害怕告诉我有些概念很难弄懂。在线讨论中就可以提问。
The course is organized into 14 weekly units. Every week, you will independently work through about 10 videos, each about 10 minutes long. Practice questions after each video will help to solidify the key concepts, and at the end of the week, you will complete a set of homework problems to tie everything together. To do well in this course, you should expect to devote about 10 hours every week to it, including time spent watching the videos.
课程按14周设置。每周10个视频左右，每个10分钟。每节课后做习题可以帮助你理解概念，每周末你需要完成一套家庭作业以回顾本周内容。想取得好成绩，你每周需要花约10小时（包括观看视频的时间）。
教学条件
参考资料This course is based on two textbooks (课程内容基于两本教科书)：
"Matter and Interactions"
Ruth Chabay and Bruce Sherwood
(3rd edition - Wiley 2011)
"Physics for Scientists and Engineers - a Strategic Approach"
