X-rays & Compton Scattering

PHY 3612008-01-18

Outline

particle-wave duality

review – blackbody radiation

review – photoelectric effect

X-ray tube – Roentgen

Bragg scattering

characteristic X-ray spectra

Compton effect

Wave Particle Duality

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

Light behaves as both a wave and a particle at the same time!
