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.

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.
Coherent sources are sources of waves that have a constant phase difference between them. An example of coherent sources is two identical lasers emitting light waves with the same frequency and wavelength.
To produce two coherent sources of light, you can use a laser to create a beam of light with a single frequency and direction. By splitting the laser beam into two using a beamsplitter, you can then generate two coherent sources of light that have the same frequency and phase relationship.
A flashlight is not classified as either a Fresnel or a Parnell light. Fresnel and Parnell are specific types of stage lighting fixtures used in theater and film production. Flashlights are portable sources of illumination that use batteries to power a light bulb or LED.
To make two coherent source for interference .Biprism make two sources.
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.
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.

Coherent sources are those that radiate waves with same phase or constant phase difference. They're very much essential for producing Fresnel's type of diffraction.

Examples of coherent sources include lasers, superluminescent diodes, and optical fibers. These sources produce light waves that are in phase with each other, leading to interference patterns and constructive interference.
Coherent sources are sources that emit light waves with a constant phase relationship. Conditions for coherence include having the same frequency, wavelength, and waveform, as well as a constant phase difference between the sources. This coherence allows for interference effects to occur, resulting in patterns such as diffraction and interference fringes.
