Fresnel biprism can be used to to determine the wavelength of given monocromatic with help of expression , λ = dβ/D
Where d is the separation between two point sources and D is the speration between source and screen and β is the fringe width as shown in figure.
Hence , wavelength of monocromatic light depends upon
1. fringe width.
2. separation between sources and sources.
3. Speration between source and screen.

Hello Dear.
Here is Your answer---
A Fesnel Biprism is a thin Double Prism placed base to base and have a Very small Refracting angle.It is used to Determine the Wavelength(λ) of a monochromatic Light Source.
The Formula which determine the Wavelength is λ = βd/D
Where,
λ = Wavelength
β = Fringe Width
d = Distance between two Virtual Sources.
D = Distance between the source and the Eyepiece.
From the Formula, we can Predict that, Wavelength of the Monochromatic light Depends upon---
a). β - Fringe Width.
b). Distance between the source and the virtual source.
c). Distance between the source and the eyepiece.
Hope it helps.
Have a Marvelous day.
