Q. Whats the difference between photoelectric effect and Compton scattering? A. Kinetic Energy transferred between photon and another material is photoelectric effect. Compton scattering demonstrates momentum.

Complex math tricks n tips

  • Use exp. notation to find square root

Important results so far

  • Copenhagen philosophy of quantum physics
    • Measure probability many many times, and look at the statistics of the results
    • The probability density relates to wave functions
    • The expectation value is a poor way to put it. It is the average
      • The measurement of observable q is solved with the integral of the wave function conjugate q and the wave function
    • The uncertainty of the measurement is aka the standard deviation which is calculated from the probability density
  • We can construct any function we like out of traveling waves, with a well-defined wave vector and wavelength and momentum
  • How “much” of each wave you want to add in?
