Monoenergetic electrons are incident on a single slit barrier.If the energy of each incident electron is increased the central maximum of the diffraction pattern:

Question

Quizplus · Accepted Answer

The width of the central maximum in the diffraction pattern is dependent on the wavelength of the incident electrons, which is inversely proportional to their energy. As the energy of the electrons is increased, their wavelength decreases, and therefore the central maximum narrows.
