X-rays & Compton Scattering PHY 361 2008-01-18
Outline • particle-wave duality • review – blackbody radiation • review – photoelectric effect • X-ray tube – Roentgen • Bragg scattering • characteristic X-ray spectra • Compton effect
PARTICLE properties interaction dynamics: F=ma mass – quantization position(time) – localized COMMON properties velocity conservation of energy, momentum WAVE properties interference – superposition dynamics: wave equation standing waves – modes wavelength, frequency reflection, transmission refraction – dispersion diffraction – Huygens oscillating medium polarization Wave Particle Duality Light behaves as both a wave and a particle at the same time!
Review – blackbody radiation density of modes average energy per mode “high frequency photons cost too much energy”
