Thin film interference - light reflects off two surface interfaces of thin film and interferes
Review how interference works between two waves
Remember/review wavelength in medium is different from wavelength in vacuum
Remember/review phase change of reflected light is 0 or 180 degrees depending on whether the light is passing from high-n to low-n or vice versa

Two slit interference
Review how two slit interference works. What is relevant equation for constructive/destructive interference at screen?
Problem is direct application of the equation.

Matter waves and deBroglie wavelength
Must relate wavelength of electron to its energy (use eqns 17-12, 17-13)
Neutron crystallography and electron microscopes are tools these students should be familiar with. What are the uses of such tools? What energy beams would be useful for evaluating crystal structure using diffraction or using electrons to image a small biological structure? Why use neutrons and electrons rather than light???
