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.

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.

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

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.

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

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

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.

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.

The Corbino effect The Corbino effect is a phenomenon involving the Hall effect, but a disc shaped metal sample is used in place of a rectangular one.

Since physical objects have wave like properties (at the atomic level), diffraction also occurs with matter and can be studied according to the principles of quantum mechanics.

Fair enough.

The anomalous Hall effect can be either an extrinsic (disorder related) effect due to spin dependent scattering of the charge carriers, or an intrinsic effect which can be described in terms of the Berry phase effect in the crystal momentum space ( k space).

Research and development was carried out by Rohr, Inc., Garrett AiResearch and Grumman.

The minimum spot size on which a laser can be focused is limited by diffraction, and depends on the wavelength of the light and the numerical aperture of the lens used to focus it.

At that time ground based telescopes were limited to resolutions of 0.5 1.0 arcseconds, compared to a theoretical diffraction limited resolution of about 0.05 arcsec for a telescope with a mirror 2.5 m in diameter.
