## How is fringe width in Young’s double-slit experiment calculated ?

fringe width in Young’s double-slit experiment is calculated using formula β = λD/d where d is the distance between two coherent sources, D is the distance between slits and screen or photodetector and λ is the wavelength. Note that fringe width is directly proportional to wavelength and inversely proportional to the distance between the two slits.

## How to Calculate Fringe Width?

Fringe Width calculator uses Fringe Width=(Wavelength*Distance between slits and screen)/Distance between two coherent sources to calculate the Fringe Width, Fringe Width is the distance between two maxima of successive order on one side of the central maxima. Fringe Width and is denoted by β symbol.

How to calculate Fringe Width using this online calculator? To use this online calculator for Fringe Width, enter Wavelength (λ), Distance between two coherent sources (d) and Distance between slits and screen (D) and hit the calculate button. Here is how the Fringe Width calculation can be explained with given input values -> 400 = (2*0.2)/0.1.

### FAQ

What is Fringe Width?
Fringe Width is the distance between two maxima of successive order on one side of the central maxima and is represented as β=(λ*D)/d or Fringe Width=(Wavelength*Distance between slits and screen)/Distance between two coherent sources. Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire, Distance between two coherent sources is the length at which both coherent sources are placed.Two sources that vibrate with a fixed phase difference between them are said to be coherent and Distance between slits and screen or photodetector is the large distance at which the slits and screen in Young's double-slit experiment.
How to calculate Fringe Width?
Fringe Width is the distance between two maxima of successive order on one side of the central maxima is calculated using Fringe Width=(Wavelength*Distance between slits and screen)/Distance between two coherent sources. To calculate Fringe Width, you need Wavelength (λ), Distance between two coherent sources (d) and Distance between slits and screen (D). With our tool, you need to enter the respective value for Wavelength, Distance between two coherent sources and Distance between slits and screen and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
