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 ...

A new atom camera uses one ultracold rubidium atom to map light intensity and polarization with spatial resolution below 100 nanometers.

Today, astronomers seek to observe the faintest and most distant objects possible. Extremely Large Telescopes (ELTs), with apertures in the order of several dozen meters, are the next generation ...

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 ...

When a laser beam is incident on a narrow opaque object such as a fine wire or a strand of hair, the resulting diffraction pattern is similar to the diffraction pattern of a slit of the same width as ...

Description: Electron diffraction patterns for single crystal and polycrystalline materials are displayed on a CRT screen. A Welch model 2639 'Electron Diffraction tube' is used in an experiment in ...

One of the coolest things about physics is that the same basic concept can pop up in several seemingly unrelated things: say, a CD, the seed shrimp’s antennae, certain fossils in the Burgess shale, ...
