The mirror of Michelson interferometer is moved a length equal to the wavelength of incident light Find the shift in fringes?
TabishAhmed
two fringes ....
since each half a wavelength distance corresponds to a fringe change!

Why circular fringes are obtained in michelson interferometer?
The mirrors are perfectly perpendicular
Why do you get circular fringes in fabry perot experiment?
In michelson interferometer the mirros are perpendicular and because of our eye viewed direction and angle theta the fringes are circular
What is meant by non-localized fringe?
Waves traveling through space interfere and produce visible fringes if the conditions are right. In particular, the waves must have some degree of spatial and temporal coherence over a region of space. Fringe localization defines the region of space where interference occurs and fringes with reasonably good contrast are observed. The location of this region relative to the components of the interferometer depends on properties of the source and geometry of the interferometer. In this section, basic properties of fringe localization are illustrated for various types of sources and interferometers. one can divide the different degree of localization in the following way: 1) Localized everywhere: The fringes have high visibility everywhere in the observation space. (Also called non-localized or unlocalized.) 2) Localized: The fringes have high visibility over some surface in the observation space. The fringe localization surface can be curved. 3) Localized at infinity: A lens is used to transform the angular distribution of fringes into a spatial distribution of fringes on an observation plane with high visibility. The observation plane is usually at the back focus of the lens. Otherwise, fringe visibility is too low for observation. (Also called Haidinger's fringes or fringes of equal inclination.) 4) Fringes of equal thickness: Localized fringes, where fringes correspond to contours of constant thickness between two surfaces.
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

What happens when a silver plate is used in newton's rings experiment?
fringes will shift because path differnce of wavelength/2 will remove.
What is the discovery of Thomas Young about light?
thomas young carried out his (double slit experiment) where he discussed the interference of light waves using monochromatic light . the 2 slits act as 2 coherent sources which emit light with same amplitude frequency . interference fringes appear due to superposition of light . this experiment is also used to determine the wavelength of monochromatic light. from the relation y=wavelength*distance between 2 slits /distance between the 2 slits and the screen where the fringes appear . where y is the distance between 2 successive bright or dark fringes.
Why are the fringes called non localized?
When the reflected ray of resulting interference is parallel by which fringes formed at infinity then this type of fringes is known as non localised fringes
What does fringes mean?
fringes are bangs (worn as a hairstyle)
When was The Fringes of the Fleet created?
The Fringes of the Fleet was created in 1916.
How can you use the word fringes in a sentence?
The movie had a song about a surry with fringes on the top. The mountain man wore a leather coat with fringes.
What is a sentence for fringes?
the added fringes give the drapes a classical French style.
