Target entity: Bragg diffraction Context triple: [Davisson–Germer experiment, usedConcept, Bragg diffraction]
-
A.
Bragg's law
chosen
Bragg's law is a fundamental equation in X-ray crystallography that relates the angles at which X-rays are diffracted by crystal lattice planes to the spacing between those planes.
-
B.
Fraunhofer diffraction
Fraunhofer diffraction is the far-field diffraction pattern of waves, typically light, observed when both the source and observation screen are effectively at infinite distance or made so with lenses, producing characteristic interference patterns.
-
C.
Bragg
Bragg is a surname most famously associated with physicists William Henry Bragg and his son Lawrence Bragg, pioneers of X-ray crystallography and Nobel Prize laureates.
-
D.
Debye–Scherrer method
The Debye–Scherrer method is an X-ray powder diffraction technique used to determine the crystal structure and lattice parameters of polycrystalline materials.
-
E.
Poisson spot
Poisson spot is a bright point of light that appears at the center of the shadow of a circular object due to wave diffraction, providing striking evidence for the wave nature of light.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
Provenance (3 batches)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
