Abstract
THE writer has found the following simple arrangement well adapted for the study of the visibility of fringes arising from a double slit and a “source” slit of variable width. A double slit, ruled without any special care on a piece of old photographic negative, was placed on the table of a spectrometer after the usual adjustments had been made. With this arrangement and a sodium flame (Mecker burner) as the source of light, no difficulty was experienced in observing the disappearance and reappearance of the fringes, with gradually decreasing visibility, some seven times.
