WebLet the angular position of n th bright fringe is θn, and because of its small value, tan θn ≈ θn. tan θ n = λ n d. ⇒ θ n = n λ d. Similarly, the angular position of (n+1) th bright fringe is θn+1, then. θ n + 1 = ( n + 1) λ d. ∴ The angular width of a fringe in Young’s double slit experiment is given by, http://pressbooks-dev.oer.hawaii.edu/collegephysics/chapter/27-5-single-slit-diffraction/
WebAug 30, 2015 · In a single slit experiment, the fringes are not equally spaced and aren’t of equal widths—the central maximum is the widest, the secondary maxima grow narrower and narrower outward, and the …
