Fringe Width. The distance between two adjacent bright (or dark) fringes is called the fringe width. β = λD/d. If the apparatus of Young’s double slit experiment is immersed in a liquid of refractive index (μ), then the wavelength of light and fringe width decreases ‘μ’ times.
The fringe width is the distance between two successive bright or dark fringes. The distance between two fringes can be calculated by β = λD d where, β represents fringe width, λ represents wavelength, D represents distance between slit and screen, and d represents the distance between two slits.
Dec 18, 2022 · If we know the value of “D” and “d” then the measurement of the fringe width (β) gives a direct determination of the wavelength of light. Fringe width formula in Young’s experiment is given by: β=λD/d
Fringe width is the distance between two consecutive bright spots (maximas, where constructive interference take place) or two consecutive dark spots (minimas, where destructive interference take place).
Jul 21, 2023 · To calculate the fringe width in Young’s double-slit experiment, you can use the formula: fringe width = (wavelength of light * screen distance) / ( slit separation ). Simply plug in the values for the wavelength of light, screen distance, and slit separation to obtain the fringe width.
Feb 20, 2022 · Young’s double slit experiment gave definitive proof of the wave character of light. An interference pattern is obtained by the superposition of light from two slits. There is constructive interference when d sinθ = mλ(form = 0, 1, −2, 2, −2,...) d sin. .
Sep 12, 2022 · The diffraction pattern of two slits of width \(a\) that are separated by a distance d is the interference pattern of two point sources separated by d multiplied by the diffraction pattern of a slit of width \(a\). In other words, the locations of the interference fringes are given by the equation \[d \, \sin \, \theta = m \lambda \nonumber \]
The distance between adjacent bright fringes is called the fringe width (x) and this can be used in the equation as: Wavelength (λ) = xd/D Fringe width (x) = λD/d

A double-slit experiment is setup with two slits 0.8 mm apart and the screen placed 70 cm from the plane of the slits. When monochromatic light is shone on the slits, it's seen that the tenth bright fringe is 5.6 cm from the central bright fringe.
