-Write the different ways to represent drift velocity (in equations).
-What is n and r? How and why do they vary from material to material?
-Describe how scattering occurs and what drift velocity is? How does temperature affect them?
-What is the difference between destructive and constructive interference?
-What is a photoemitted electron?
-Describe the photoelectric effect? What does the set-up look like (anode, cathode, target material). Where do the emitted electrons come from?
-What is no and why does it vary from material to material?
-Compare the relationships of the saturation current from photoemitted electrons and the kinetic energy on the light intensity. What does this tell you about intensity? What does this have to do with photons?
-The de Broglie relationship relates an electron with momentum p to what?
-What does the square of the wave function represent?
-What is a complex conjugate?
