If an electron has an energy such that its de Broglie wavelength is 5500 Å , then the energy value of that electron is (h= 6.6 xx 10^(-34)) Js, m_( c) = 9.1 xx 10^(-31) kg

For given enegy, corresponding wavelength will be E = 3.03 xx 10^(-19) Joules (h = 6.6 xx 10^(-34) j X sec., C = 3 xx 10^(8) m/sec
