diffraction

X-ray diffraction — an imaging tool that reveals the arrangement of individual molecules — shows that the polymers change from their messy non-crystal phase at warm temperatures to an orderly crystal phase when they’re cooler.

Crystals were not the only possible forms of matter with orderly arrangements of atoms and pinpoint diffraction patterns.

It was unlike any other diffraction pattern that Feynman had ever seen.

The four-arm secondary mirror bracket helps cut down on light loss and diffraction spikes.

X-rays are then fired at these crystals, allowing a scientist to work backward from the diffraction patterns they make to build up a picture of the protein itself.

The phenomenon is purely optical, involving diffraction of light.

It is therefore certain that this is a phenomenon of the diffraction of light simply produced by the vesicles of the mist.

X-ray-diffraction studies showed no material differences, nor were there detectable differences in “feel”, smell, or plasticity.

Perfect transparency is obtained since there is neither refraction nor diffraction of the visible colors.

This diffraction of light first proved to us definitely the reality of the undulatory theory of light.
