In classical physics, this phenomenon is explained using Huygens’ principle. For 10 points each:
[10e] Name this phenomenon which occurs when light passes through a namesake grating. Light can bend around corners when undergoing this phenomenon, which caused an interference pattern in Young’s double slit experiment.
ANSWER: diffraction [accept diffraction grating]
[10m] This law governs the diffraction of x-rays in a crystal. It states that diffraction order times wavelength equals two times the grating constant times sine of theta.
ANSWER: Bragg’s Law
[10h] The results of this experiment agreed with the prediction of Bragg’s Law. Electrons diffracted off a nickel crystal in this experiment, which provided evidence for wave-particle duality.
ANSWER: Davisson-Germer experiment
