WebSep 19, 2024 · To get interference, you need a precise path difference between two beams of light. If you have a wide slit, light could have passed in many places - and from there to the screen there are many different path lengths possible. When this happens, you don't get a clear interference pattern. WebMar 4, 2013 · The build-up of the interference pattern with single electrons has been demonstrated by replacing the two-slit interferometry device with an electrostatic biprism, i.e. a thin charged wire whose field acts on electrons in a similar way to that in which a Fresnel biprism acts on light [ 6 – 8 ].

WebJun 1, 2014 · Biprism interferometry In biprism interferometry [23] an ideally point-like electron or ion source illuminates coherently a biprism fiber. Applying a positive (for electrons) or negative (for ions) potential on the wire leads to a separation and a deflection of the matter wave.

WebNov 19, 2015 · Interference is the periodically changing energy distribution along a line or area (the observation screen) of light behind slits or even every edge. For water waves one use a similar terminology. Diffraction is the change of movement of the maximum and minimum high of the water level behind edges, but not behind single edges.
