Quizplus · Accepted Answer

Davisson and Germer first observed wavelike interference and diffraction effects in the scattering of electrons by a crystalline target in 1927, known as the Davisson-Germer experiment. A and C are not related to this experiment, while B and D are related to the wave-particle duality theory but not specific experiments involving electron diffraction.
