And as a reminder, hopefully I don't need to remind any of you, but exam 1 is on Wednesday, so rather than our clicker question being on something from last class, which is exam 2 material, let's just make sure everyone remembers some small topic from exam 1 material, which is the idea of angular nodes.
而作为一个提醒--我希望大家都不需要提醒,但是这周三就要进行第一次考试了,因此我们的这个选择题,不是关于上节课内容的,那是第二次考试的内容,这里只是想确认大家都记得,第一次考试所要求的一些小问题,也就是关于角向节点的概念。
- There are a few equations that you need to memorize -- those are the very simple -- very, very simple equations, such as e equals h times nu -- hopefully you don't have to sit down and try to memorize that, hopefully we all know that already.
只有几个公式是需要记住的-,它们都非常简单,非常非常简单,比如,E,等于,h,乘以,ν,希望大家不需要再专门去背了,希望我们已经都记住了。
