Primarygun Posted March 23, 2005 Share Posted March 23, 2005 http://www.geocities.com/thesciencefiles/singleslit/diffraction.html] Refer to this web site, please. The brightness of the colour is proportional to its amplitude? I can understand why the middle of the screen is the brightest, but in my mind, I think there should be only one area which is bright for a single-slit. Is that light has many beams and able to create interference for even only a single-slit? The diffraction of a light beam is really different from that of a water wave, isn't it?

Primarygun Posted March 23, 2005 Author Share Posted March 23, 2005 Oh sorry, I can't find it again. Do interferences occur when a light passes through a single slit by diffraction? Only one area is bright ? or Several areas are bright projected on a screen? Link to comment Share on other sites More sharing options...
swansont Posted March 23, 2005 Share Posted March 23, 2005 Yes interference occurs, because the slit is of finite width. (add) and the path length varies. Link to comment Share on other sites More sharing options...

swansont Posted March 24, 2005 Share Posted March 24, 2005 Thank you.The diffraction of a light beam is really different from that of a water wave, isn't it? They both diffract and interfere. Here and here are ripple-tank experiments that show the interference effects in water. Link to comment Share on other sites More sharing options...
