An electron and alpha particle have the same kinetic energy. How are the De broglie wavelength associated with them related ? Share with your friends Share 1 Vara answered this Debroglie wavelength:λ=hp =h2mEkHere,h is Planck's constant,m is mass,andEk is kinetic energyFor a given kinetic energy,λ α 1mλelectronλalpha=malphamelectron =2melectronmelectron [ since malpha = 2 × melectron ] =2Hence,λelectron=2λalpha 8 View Full Answer Ashuvendra answered this compare the mass .. 1 Ashuvendra answered this mass of alpha particle is twice of electron 0
