Problem

In a Davisson–Germer experiment the principal diffraction maximum is observed at

50^{\circ}

when the electrons are accelerated through

54\,\text{V}

. Predict qualitatively what will happen to the position of this maximum if the accelerating voltage is increased to

100\,\text{V}

and give a brief reason.
