## What is optical path difference ?

In the thin glass slab of thickness t and refractive index μ, and the optical path of the ray increases by t( μ -1 ) where t is the thickness of the slab. So path difference between waves coming from two coherent sources at any point P is Δ = (μ - 1 ) D/d = ( μ -1 )t β / λ.

### FAQ

What is Optical path difference when fringe width is given?
Optical path difference when fringe width is given is the product of the geometric length of the path followed by light through a given system, and the refractive index of the medium through which it propagates and is represented as Δ=(RI-1)*T*β/λ or Optical path difference=(Refractive Index-1)*Thickness*Fringe Width/Wavelength. The refractive index of a medium is defined as how the light travels through that medium. It is a dimensionless measure. It defines how much a light ray can bend when it enters from one medium to the other, Thickness is the distance through an object, Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire and Fringe Width is the distance between two maxima of successive order on one side of the central maxima.
How to calculate Optical path difference when fringe width is given?
Optical path difference when fringe width is given is the product of the geometric length of the path followed by light through a given system, and the refractive index of the medium through which it propagates is calculated using Optical path difference=(Refractive Index-1)*Thickness*Fringe Width/Wavelength. To calculate Optical path difference when fringe width is given, you need Refractive Index (RI), Thickness (T), Wavelength (λ) and Fringe Width (β). With our tool, you need to enter the respective value for Refractive Index, Thickness, Wavelength and Fringe Width and hit the calculate button.
