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.
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.
Jun 25, 2021 · Fringe width is the distance between two consecutive bright spots (maximas, where constructive interference take place) or two consecutive dark spots (minimas, where...
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.
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).

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 \[d \, \sin \, \theta = m \lambda \nonumber \]
Dec 18, 2022 · This eqn. (4), ‘β=λD/d’ is called Fringe width formula in Young’s experiment. From eqns. (2) and (4), it is evident that the fringes width of bright fringe and dark fringe is the same. 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.
Each bright fringe is identical and has the same width and intensity; The fringes are all separated by dark narrow bands of destructive interference; The constructive and destructive interference of laser light through a double slit creates bright and dark strips called fringes on a screen placed far away. Interference Pattern
The fringe width gets affected by the light wavelength and even by the distance between the flat screen or “separation of slits” and the slits.
