A proton, a neutron, an electron and an α-particle have same energy. If λp, λn, λe and λα are the de Broglie’s wavelengths of proton, neutron, electron and α particle respectively, then choose the correct relation from the following:
1
λp = λn > λe > λα
2
λα < λn < λp < λe
3
λe < λp = λn > λα
4
λe = λp = λn = λα
