K. Mitra on the Problem of The fourth column in the Table gives the positions of themaxima and minima of illumination measured on a photo-graph taken of the fringes due to a screen grazed by theincident rays. They agree closely with the theoretical valuesgiven in the third column. The ratios of the intensity of illumination at the maximaand minima have been determined photometrically for com-parison with the theoretic
