justification of dual nature of electron Particle nature : when an electron strikes a ZnS screen it produced a spot called scintillation .which is localised and spread like a wave .this suggested that electron behave like a particle. wave nature : when electrons we're made to strike against nickel crystal, concentrating ( having common centre) were formed these rings are called diffraction rings. this explains wave nature of electron. some important values: c = velocity of light =3×10^8m/s. h= Planck constant =6.626×10^-34kgm^2s^-2. √= wavelength (lamda) v= frequency =c/√ numerical related to de broglie principle in next page
