The coherence length of black
... coherence length is slightly less than the mean or effective wavelength. That is why no fringes (modulation of intensity) of order |m| � 1 occur. So, in the case of unfiltered black-body radiation, interference patterns consist only of a central maximum (m = 0) flanked by two weak minima (m = ± 21 , s ...
