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.
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 destructive...
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 17, 2024 · Fringe width is the distance between two consecutive dark and bright fringes and is denoted by a symbol, β. Fringe width depends on the following factors that are outlined below: The wavelength of light. The distance between the slits and the screen or slit separation.
(c)As d increases, fringe width (ω ∝ 1/d) decreases (d)The interference pattern due to different component colours of white light overlap (in-coherently). The central bright fringes of different colours are at the same position.
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 \[d \, \sin \, \theta = m \lambda \nonumber \]
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.
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
Let's solve a couple of questions on fringe width in double slit interference. Created by Vibhor Pandey.
