WebMar 6, 2024 · The fringes are visible only in the common part of the two beams. By neglecting the distance between the slits, the angular width associated with the diffraction is 2 ( λ / a) and the angular width of a fringe is λ / d As the central fringe is bright, we will roughly have N = 1 + 2 d / a visible fringes. WebNov 20, 2024 · Thus the total fringe width is equal to the 1/2 the width of one light band, plus the width of a dark band, plus a second 1/2 the width of one light band. Which is equivalent to the width of one light band plus … WebFringe is the alternating light and dark band that forms as a result of interference. The formula is used to calculate the fringe width β = λD d Where, β represents the bandwidth, λ represents wavelength of the light, D represents the distance between the source and the screen, d represents distance between the two slits in both dna and rna heterocyclic base
