We will talk about "standing waves" today!

Quantum physics recognizes that light behaves like particles and waves. Louis de Broglie proposed that if light, which we typically think of as a wave, has particle like behaviors why then can't things we think of as having particle like behavior act as waves also? Think about this! de Broglie proposed that when you throw a baseball, that that baseball has a WAVELENGTH!!! Of course, de Broglie was more interested in the behavior of electrons than baseballs, but the concept is the same- particles can be describes as waves.

In this lecture we will be looking at the wave properties of electrons. And as a bonus, you get to use the equation E=mc². How many people do you know who have done that!?
