1.	De Broglie poroposed that moving micro particles exhibit wave behaviours. Electron in a Bohr.s orbit also shows dual nature whose wave length is given by lambda_(e) = (h)/(m_(e)V_(e)) m_(e) = mass of electron , V_(e) = velocity of electron , h = planck.s constant Bohr.s atomic model is in good agreement with De-broglie concept and the electron has fixed energy in Bohr.s orbit : 2pi r = n lambda (constructive wave in phase). The kinetic energy of an electron in alpha Bohr.s orbit of H-atom is 3.4 eV. What is the its De-broglie.s wave length ?
