Positronium shouldn't last long enough to be interesting. It's an "atom" assembled from an electron and its antimatter twin — ...

What happens when a wave passes through some opening? It diffracts - or you like, you could say "bends". If the size of the opening is comparable to the wavelength of the wave, the bending can be ...

Single-crystal diffraction was invented 100 years ago by Max von Laue. It has since become a workhorse technique for chemists to determine the structures of organometallic complexes and other ...

Using ultrahigh-intensity x-ray beams can cause the intensity of diffraction patterns from samples to drop Figure 1: An x-ray diffraction pattern obtained from a sample of Martian soil. X-ray ...

The (relatively) ancient art of crystallography has had a huge impact on modern science by showing us the location of atoms within a molecule. The structure of DNA (and how it acts as an information ...

When a laser beam is incident on many small objects such as lycopodium powder, the resulting diffraction pattern is similar to the diffraction pattern of a small circular aperture (Airy's disk pattern ...

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 ...

Nobody knows what the surface of neutron stars are made of but there’s no shortage of suggestions. We know that iron must play a role because we can see its characteristics absorption lines in the ...
