-
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.
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.
-
C.
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.
-
D.
Sievers' law
Sievers' law is a historical phonological rule in Indo-European linguistics that explains the alternation between consonantal and vocalic forms of certain sounds (notably *y and *w) depending on the weight of the preceding syllable.
-
E.
X-rays and Crystal Structure
"X-rays and Crystal Structure" is a foundational scientific work by Lawrence Bragg that explains how X-ray diffraction can be used to determine the atomic structure of crystals.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
