દ-બ્રોગ્લી તરંગલંબાઈ \(\lambda \,\, = \,\,\frac{h}{p}\,\, = \,\,\frac{h}{{\sqrt {2mE} }}\,\,\,\,\,\)

\(\therefore \,\,E\,\, = \,\,\frac{{{h^2}}}{{2m{\lambda ^2}}}\,\,\,\lambda \) અચળ હોવાથી  \({\text{E}}\,\, \propto \,\,\frac{{\text{1}}}{{\text{m}}}\)

અહીં \({\text{, }}{{\text{m}}_{\text{e}}}{\text{  <  }}{{\text{m}}_{\text{p}}}\) 

હોવાથી \({{\text{E}}_{\text{e}}}{\text{  >  }}{{\text{E}}_{\text{p}}}\)
