An extremely small hole, however, can produce significant diffraction effects and a less clear image due to the wave properties of light.

XRF, X ray diffraction, and the results are very positive so far.

While diffraction occurs whenever propagating waves encounter such changes, its effects are generally most pronounced for waves whose wavelength is roughly comparable to the dimensions of the diffracting object or slit.

History The effects of diffraction of light were first carefully observed and characterized by Francesco Maria Grimaldi, who also coined the term diffraction , from the Latin diffringere , 'to break into pieces', referring to light breaking up into different directions.

The first X ray diffraction pictures of the crystallised virus were obtained by Bernal and Fankuchen in 1941.

Usually these are transitions from upper shells into K shell (called K lines), into L shell (called L lines) and so on.

The best pinhole is perfectly round (since irregularities cause higher order diffraction effects), and in an extremely thin piece of material.

When one pinhole is closed, the grid of wires causes appreciable diffraction in the light, and blocks a certain amount of light received by the corresponding photon detector.

Then the dark, rich part of the flower has a diffraction grating, like you'd find on a CD, in the center, overlying the center of the flower.

In 1969, after decades of work, Dorothy Hodgkin determined the spatial conformation of the molecule, the so called tertiary structure, by means of X ray diffraction studies.

Grazing incidence diffraction is used in X ray spectroscopy and atom optics, where significant reflection can be achieved only at small values of the grazing angle.

Also in 1923, Debye developed a theory to explain the Compton effect, the shifting of the frequency of X rays when they interact with electrons.
