Problem 2.12. Assume that the de-Broglie wave associ-ated with an electron can form a standing wave between theatoms arranged in a one dimensional array with nodes ateach of the atomic sites. It is found that one such standingwave is formed, if the distance d between the atoms of thearray is 2 A. A similar standing wave is again formed, if thedistance d is increased to 2.5 A, but not for any intermediatevalue of d. Find the energy of the electrons in eV and theleast value of d for which the standing wave of the typedescribed above can form.LIT 1997
