Problem
In an electron diffraction experiment, a strong first-order peak is observed at a scattering angle of 44° when the accelerating voltage is V. If the accelerating voltage is increased to 4V, at which angle will the same order peak now appear (crystal unchanged)?
(a) 12∘
(b) 20∘
(c) 44∘
(d) 70∘
