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 phenomenon is similar to the Gibbs phenomenon in Fourier series approximations.

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

A strange phenomenon.

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.

This phenomenon is called haplodiploidy.

But from a mythological outlook, whether or not the event actually occurred is unimportant.

It's an amazing phenomenon.

It's a normal phenomenon.

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

This phenomenon is very easy to explain.

This phenomenon is known as the cremasteric reflex.

This phenomenon is called dichromatic color.

Citizen Media Phenomena

This phenomenon isn't new.

This phenomenon is also called evaporative cooling.

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

Then you look at the phenomenon of Kogi.

Henriapi illustrates this phenomenon as well.

I'm a representation of that phenomenon.

How can we explain this strange phenomenon?

Snobbery is a global phenomenon.

Nobody has been able to scientifically explain the phenomenon.

This is called boiling point elevation.

There is a presumption of liberty of individuals that is restrained.

This is a piece that I just recently completed about another tragic phenomenon. And that is the phenomenon, this growing obsession we have with breast augmentation surgery.

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.

I'm going to show you just a few examples of how pervasive this phenomena is.

That was strictly a capital markets phenomena.

And this isn't some new phenomenon of our wired world.

And what you see is a scaling phenomenon.

The term includes nuclear fission, nuclear decay and nuclear fusion.

The mass was about thick and it travelled downward at a rate of .

And this is a very widespread phenomena.

So it's not simply a Western phenomenon.

So, a new social phenomenon is emerging.

It's an extraordinary phenomenon, but it's true.

The phenomenon soon became a worldwide joke.

A rainbow is a natural phenomenon.

In physics, interference is a phenomenon in which two waves superpose to form a resultant wave of greater or lower amplitude.

And actually this is just one example of a much larger phenomenon.

Child labour in Brazil is a phenomenon of an eminently rural nature.
