To use this online calculator for Fringe Width, enter Wavelength (λ), Distance between Slits and Screen (D) & Distance between Two Coherent Sources (d) and hit the calculate button. Here is how the Fringe Width calculation can be explained with given input values -> 5107.17 = (0.268*0.202)/0.106.
Fringe Width is the distance between two consecutive bright or dark fringes in an interference pattern, typically measured from the center of a bright fringe to the center of the next bright fringe.
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.
- In Young’s experiment, the distance between the two slits is 0.8 mm and the distance of the screen from the slits is 1.2m. If the fringe width is 0.75 mm, calculate the wavelength of light.
- In Young’s experiment, the distance between the two images of the sources is 0.6 mm and the distance between the source and the screen is 1.5 m. Given that the overall separation between 20 fringes on the screen is 3 cm, calculate the wavelength of light used.
- The distance between two consecutive bright bands in Young’s experiment is 0.32 mm when the red light of wavelength 6400 Å is used. By how much will this distance change if the light is substituted by the blue light of wavelength 4800 Å with the same setting?
- Calculate the fringe width in the pattern produced in a biprism experiment given that the wavelength of light employed is 6000 Å, distance between sources is 1.2 mm and distance between the source and the screen is 100 cm.
Sep 12, 2022 · Calculate the intensity for the fringe at m=1 relative to \(I_0\), the intensity of the central peak. Strategy. Determine the angle for the double-slit interference fringe, using the equation from Interference, then determine the relative intensity in that direction due to diffraction by using Equation 4.3.11.

Calculate the fringe width for light of wavelength 550 nm in a Young's slit experiment where the double slits are separated by 0.75 mm and the screen is placed 0.80 m from them. Fringe width (x) = λD/d = 550x10-9 x0.80/0.75x10-3 = 5.9x10-4 m = 0.59 mm
