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.
