Wave Particle Duality Light behaves as both a wave and a particle at the same time! PARTICLE properties individual interaction dynamics: F=ma mass – quantization position(time) – localized mass spin COMMON properties: energy, momentum, velocity WAVE properties collective interference – superposition dynamics: wave equation standing waves – modes wavelength (freq) – periodic dispersion polarization reflection, refraction, trans. diffraction – Huygens
2
Reflection, Diffraction, Interference animation
3
Particle waves phonon photon ??? ??? ??? electron
4
Electromagnetic waves
5
Blackbody radiation – Planck, Boltzman–Stefan, Wien
energy per photon “high frequency photons cost too much energy” density of modes photons per mode
6
Photoelectric effect – Einstein
7
X-rays – Roentgen, Bragg, Laue, Duane-Hunt, Compton
8
Particle Waves – de Broglie, Davisson-Germer
9
Wave packets – Fourier, Heisenberg
10
Hydrogen atom – Rutherford, Bohr
11
Potential wells – conservation of energy
12
