Question

what is localized and non localized fringe.? give example..... if you have any pictures about this then show me

Answer 1

When coherent light rays mix together they create fringes in some areas and they are called localized fringes.

If the fringes are seen in the whole area of observation then it is called non-localized fringes.

Coherence is spatial and temporal symmetry.

Answer 2

Answer:

Explanation:

Localized fringes:

Localized fringes are created when coherent light rays collide, and they appear as fringes in some places.

Non localized fringes:

In an extended (three-dimensional) region of space, nonlocalized fringes can be found everywhere. For instance, in Young's double slit experiment, actual fringes fill the area beyond the secondary sources. As a result, these fringes are truly nonlocalized in that they are not confined to a particular small area of space. Small sources, such point or line sources, typically produce these kinds of fringes. Localized fringes, on the other hand, are unmistakably visible only across a certain surface, whether close to a thin layer or at infinity. These fringes are produced by the employment of extended sources, however point sources are equally capable of producing them.
