A fresnel biprism is a triangular right prism with a highly obtuse angle in cross-section. The obtuse angle is near 180 degrees. The typical use of such a prism is to produce two coherent "virtual" light sources from one real point source. These virtual sources can be used to demonstrate interference.

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.
Why do you use biprism in fresnel biprism experiment?
To make two coherent source for interference .Biprism make two sources.

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
