State two effects to show (a) the existence of matter waves; (b) that radiation behaves like particles.
Explanation
a) Effects to show the existence of matter waves: - diffraction of electrons — diffraction on neutron from crystal surface — diffraction pattern by reflecting hydrogen and helium molecules from crystal surface.
(b) Effects to show that radiation behaves like waves: — compton effect — photoelectric effect — black body radiation — emission/absorption spectra — quantization of radiation energy proposed by Planck.
