The intensity distribution curves in three-beam interference between three rectangular slits in a beam of quasi-monochromatic light from an incoherent slit source are investigated by the photo-electric method with Ebert optical system. Examples and discussions are given to illustrate the relation between the widths of primary slit source and the patterns. We must take note of that no fringe disorder is in the patterns with some special primary source widths and that the fringe disorder, if it exists, always comes up either at the parts of intensity maxima or at the parts of intensity minima of the patterns.
