Behavior Of Waves
... Diffraction is the bending of a wave around a barrier or around the edges of an opening. Waves with a longer wavelength diffract more readily. In order to observe light diffraction the barriers or openings must be small. When light waves diffract, interference patterns can often be observed. ...

Two-Beam Interference Equation Interferometric optical testing is
... Most laboratory interferometers create two beams using division of amplitude beamsplitters, where the irradiance is divided across the entire wavefront such that the diameter of the beam is unchanged. This can be done using cube beamsplitters, plate beamsplitters, pellicles, and diffraction gratings ...
