Electron diffraction was revolutionary not just for fundamental physics, but led to the development of cutting-edge technology such as the electron microscope. The wave-particle duality was ...

This is diffraction - the spreading out of waves when they go through a gap, or past the edge of a barrier. The extent of the spreading (diffraction) depends on how the width of the gap compares ...

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 ...
