This diffraction causes the light to form a diffraction pattern, known as the Airy disk, at the focal plane of the microscope. The Airy disk consists of a central bright spot surrounded by concentric ...

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 ...

X-ray diffraction methods lie at the foundation ... either as part of its designed function or to test fundamental materials science principles. Shock waves, ion irradiation tracks, chemical ...

Use the lab jacks to elevate the fringe pattern to a screen, if necessary. Turn off the laser. Turn on the laser. Turn off the room light to see the diffraction pattern more easily. Point out the Airy ...
