Diffraction topics include: Light diffraction, plane diffraction grating, prism and grating spectra difference, grating resolving power, fresnel and fraunhofer diffraction. Diffraction is the bending or spreading out of waves as they pass through an obstacle or aperture. It can occur with sound, electromagnetic radiation, and very small moving particles.  Diffraction occurs when the size of the obstacle or aperture is similar to the wavelength of the incident wave. For example, when light waves pass near a barrier, they bend around the barrier and spread out.  Diffraction can also occur... Show more
