Hi ! I've done some experiments with slits in front of my SLR. It looks to me, that there is a difference between on slit and two slits. (that is contradicory to the experiments of Guillermo a few days ago) The image, that is produced by two slits seem to be clearer/sharper. (But this effekt could probably be cause by the wrong "diameter" of the single-slit.)
Has anyone of you got some new experiences ? Sebastian
