Compton scattering 5 unshifted peaks come from collision between the X-ray photon and the nucleus of the atom ’ - = (h/m N c)(1 - cos) 0 since m N >> me 18
WAVE-PARTICLE DUALITY OF LIGHT Einstein (1924) : “There are therefore now two theories of light, both indispensable, and … without any logical connection.” evidence for wave-nature of light: • diffraction • interference evidence for particle-nature of light: • photoelectric effect • Compton effect Light exhibits diffraction and interference phenomena that are only explicable in terms of wave properties Light is always detected as packets (photons); we never observe half a photon Number of photons proportional to energy density (i.e. to square of electromagnetic field strength) 19
