Let us assume that the de-Broglie wave asssociated with an electron froms a standing wave between the atoms arranged in a one-dimensional array with nodes at each of the atomic sites. If is found that one such standing wave is formed, if the distance between the atoms of the array is 3 Å . A similar standing wave is again formed, if d is increased to 3.5 Å but not for any intermediate value of d. Find the energy of the electrons in electron volts and the least value of d for which the standing wave of the type described above can from.
