Assume that the de-Broglie was associated with an electron can forma standing wave between the atoms arranged in a one dimensional array with nodes at each of the atomic sites. It is found that one such standing wave is formed if the distance d between the atoms of the array is 2 Å. A similar standing wave is again formed if d is increased to 2.5 Å but not for any intermediate value of d. Find the energy of the electron in eV and the least value of d for which the standing wave of the type described above can form.

An electron, in a hydrogen like atom , is in excited state. It has a total energy of -3.4 eV, Calculate (i) the kinetic energy and (ii) the de-Broglie wavelength of the electron.

An electron (mass m) with initial velocity vector v = v0i + v0j is in an electric field vector E = -E0k. If λ0 is initial de-Broglie wavelength of electron, its de-Broglie wave length at time t is given by
