One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the observation that matter behaves differently at the smallest scales. A key ...

In the year 1900, no one would have guessed that light — to all appearances an ethereal wave-like phenomenon — might take the form of localized particles. Nor would anyone have expected that the ...

An algorithm that enables a protein's molecular structure to be determined from the faintest of diffraction patterns could increase the potential of next-generation X-ray sources. The next few years ...

A pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not randomly, but in a coordinated rhythm, twisting and untwisting in sync like ...

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...

In 1967 the Russian physicist Victor Veselago predicted the existence of a material with a negative index of refraction, which he termed “left-handed.” He concluded that in the presence of such a ...

Do not exceed 10 mA of current! The electron diffraction tube is fragile. Handle with care. Turn down the high voltage when not in use. It is worthwhile to contrast the diffraction of electrons with ...

With the 2019 Nobel Prize for Physics due to be announced on Tuesday 8 October, Physics World journalists pick their favourite Nobel awards from the past. Here Matin Durrani argues the case for the ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...

To the recording studio to study interference and diffraction of sound waves. Unit 6 Segment D: Sound: Diffraction and Interference We head back to the recording studio to study interference and ...
