Why do you use biprism in fresnel biprism experiment?
To make two coherent source for interference .Biprism make two sources.
Is the fresnel biprism experiment better than young's double slit experiment?
yes,because in fresnel biprism the fringe width can be increased so that the dark and bright fringes can be seen clearly by naked eyes..but there is no such problem in fresnel biprism.. in young's double slit experiment, the pattern is the superposition of interference and diffraction. but in fresnel biprism it is purely interference pattern.
What happens if focal length is increased in fresnel biprism experiment?
separetion between two real images will decreases
Why you use fresnel biprism?
to find wavelength of a monochromatic light source and for determining the thickness of a thin glass sheet when placed between bi prism and screen or eyepiece
What is bench correction in fresnel biprism experiment?
in eyepeace lens is adjusted at some distance while we observe reading at some distane ffrom the eyepeace...this is call bench error
What are the uses of biprism?

Difference between Newton's ring fringes and biprism fringes?
Biprism produce straight fringe systems while Newton's rings are circular fringe patterns.
How measure angle of biprism using newton's ring?
Newton's rings are a phenomenon of interference patterns created between a flat surface and a spherical surface. The interference patterns provided by a biprism aren't rings like newton's rings, but the spacing between them can help provide some measurement to the near-180 degree angle of the biprism.
What is a biprism?
A biprism is a fusion of two triangular prisms, or an optical device employing this type of construction.
How do you find wavelength of given light source using fresnel's biprism?
Using biprism interference pattern can be produced. Therefrom the band width beta is to be measured. Now using the formula, beta = lambda*D/d Here lambda is the required wavelength of the source light. D is the distance of the screen from the virtual sources. d is the distance between the two virtual coherent sources. Knowing beta, D and d, required lambda could be calculated.
Why do you get straight fringes in fresnel biprism?
. You can read the paper describing how very clear fringes are made by Fresnel biprism well. Paper title : Compact Design of a Nomarski Interferometer and Its Application in the Diagnostics of Coulomb Explosions of Deuterium Clusters
Uses of fresnel's biprism?
to determine wavelenghts and interference fringes
