This results in a pattern of concentric bright and dark rings, interference fringes. In areas where the path length difference between the two rays is equal to an odd multiple of half a wavelength (λ/2) of the light waves, the reflected waves will be in phase , so the "troughs" and "peaks" of the waves coincide.
Haidinger fringes are interference fringes formed by the interference of monochromatic and coherent light to form visible dark and bright fringes. Fringe localization is the region of space where fringes with reasonably good contrast are observed. [further explanation needed] Haidinger fringes are fringes localized at infinity.

Colored and monochromatic fringes in a Michelson interferometer: (a) White light fringes where the two beams differ in the number of phase inversions; (b) White light fringes where the two beams have experienced the same number of phase inversions; (c) Fringe pattern using monochromatic light (sodium D lines
Formation of fringes in a Michelson interferometer This photo shows the fringe pattern formed by the Michelson interferometer, using monochromatic light (sodium D lines). As shown in Fig. 3a and 3b, the observer has a direct view of mirror M 1 seen through the beam splitter, and sees a reflected image M' 2 of mirror M 2 .
Figure 1. Fizeau interferometer. A Fizeau interferometer [1] is an interferometric arrangement whereby two reflecting surfaces are placed facing each other. As seen in Fig 1, the rear-surface reflected light from the transparent first reflector is combined with front-surface reflected light from the second reflector to form interference fringes.
Most important task of the board, among few others, is to conduct the SSC for 10th class and HSC for 12th class examinations. [2] It is the most popular education board in terms of enrollment in high school in India only after the Central Board of Secondary Education.
We imagine a screen for viewing fringes placed at the light source (or we use a beamsplitter to send light from the source point to the screen). Given a steady light source, interference fringes will form on the screen with a fringe displacement proportional to the time differences required for the two counter-rotating beams to traverse the ...
Since the focal length of the lens varies with the color of the light different colors of light are brought to focus at different distances from the lens or with different levels of magnification. Chromatic aberration manifests itself as "fringes" of color along boundaries that separate dark and bright parts of the image.
