S1 and S2 be double slits equidistance from S. Let the distance between S1 and S2 be ‘d’ and ‘D’ be the distance of the screen (AB) from S1 S2 . Let us consider a point P at a distance ‘x’ from the center ‘O’ (Fig.). 2 Condition for bright fringe: The point P is bright when the path difference is a whole number of multiple

the utilization of the single slit-diffraction phenomena in analyzing the physical characteristics of a hair strand. Hair samples with various macroscopic textures were used as barriers to produce a diffraction pattern where the distance between fringes were readily obtained using a program that displays its line profile. The eccentricity values‚ [pic]‚ are (0.12±0.01)‚ (0.29±0.04)‚ (0.33±0.01)‚ (0.35±0.03) for Sample 1 to 4 respectively. Almost all of the samples exhibit eccentricities of less than
