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. 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.

Fresnel produced the interference fringes in the laboratory by deriving two coherent sources S 1 and S 2 from a single monochromatic source S by using the deviation produced by a biprism. The experimental arrangement is shown schematically in Figure 7. The biprism consists of two acute angled prisms with their bases in ...
