Why Lesson Planet?
A simple, single page assignment asks wave masters to record the wavelength of the x-rays coming from a powder diffractometer and perform calculations with it. Equations, energy level diagrams, and a periodic table are all included. Obviously you would need to have the lab instrument to fully carry out this activity with your class. If one is not available, you could simply assign x-ray wavelengths to your class to practice with. Relevant, but not as fun.
