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 ...

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 ...

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 ...

In the field of scanning electron microscopy (SEM), the electron backscatter diffraction (EBSD) method has developed into a robust tool for the crystallographic analysis of materials. Specifically, ...

A new scientific instrument at the Department of Energy's SLAC National Accelerator Laboratory promises to capture some of nature's speediest processes. It uses a method known as ultrafast electron ...

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 ...

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 ...

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 ...
