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.
What is fresnel's biprism?
Fresnel Bi Prism is to find wavelength of monochromatic light sorce and to determine the thickness thin glass sheet placed on sorce Written by Ajay kumar
Describe fresnel biprism?
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.
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

How two coherent sources are realized in fresnel biprism?
In a Fresnel biprism setup, two coherent sources are realized by using a single source that is split into two coherent beams by the biprism. The two beams then interfere with each other to create an interference pattern. This interference pattern contains information about the phase difference between the two beams, allowing for interference effects to be observed.

Why do you get straight fringes in fresnel biprism?
Straight fringes in a Fresnel biprism setup occur due to constructive and destructive interference of light waves from the two coherent sources, resulting in alternating bright and dark fringes. The interference pattern produced depends on the path difference between the two waves and can be observed as straight fringes when the setup is aligned properly.
Uses of fresnel's biprism?
Fresnel's biprism is commonly used in experiments to study interference and diffraction of light. It can be used to produce interference fringes, measure the wavelength of light, and study wavefront properties. Additionally, it is used in optical systems for generating coherent light sources.
What happens if focal length is increased in fresnel biprism experiment?
Increasing the focal length in a Fresnel biprism experiment will result in the interference fringes becoming more widely spaced. This is because the distance between the fringes is directly proportional to the wavelength of light and inversely proportional to the focal length. Thus, increasing the focal length will increase the fringe separation.

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
How do you find wavelength of given light source using fresnel's biprism?
To find the wavelength of a given light source using Fresnel's biprism, you can use the formula: λ = x*d / D, where λ is the wavelength, x is the fringe width, d is the distance between the biprism and the screen, and D is the distance between the biprism and the light source. By measuring x, d, and D and plugging them into the formula, you can calculate the wavelength of the light source.
Why light rays bend upward and downward in fresnal biprism?
Light rays in a Fresnel biprism bend upwards and downwards due to the differing refractive indices of the two prisms, causing the light to experience different speeds and angles of refraction. This results in the phenomenon of interference patterns when the light waves reunite due to the phase difference caused by this refraction.
