Assertion (A) : The fringe obtained at the centre of screen in known as zeroth order fringe, or the central fringe Reason (R ) : Path difference between the waves from S_(1) and S_(2) , reaching the central fringe (or zero order fringe) is zero

Interference fringes are observed on a screen by illuminating two thin slits 1 mm apart with a light source (lambda=632.8 nm) . The distance between the screen and the slits is 100 cm. If a bright fringes is observed on a screen at a distance of 1.27 mm from the central bright fringe , then the path difference between the waves , which are reaching this point from the slits is close to :

If the path difference between the interfering waves is n lambda , then the fringes obtained on the screen will be

The ratio of the intensity at the centre of a bright fringe to the intensity at a point one-quarter of the distance between two fringe from the centre is

Two coherent sources of light interfere and produce fringe pattern on a screen . For central maximum phase difference between two waves will be

In Young's double slit experiment the phase difference between the waves reaching the central fringe and fourth bright fringe will be

In Young's double slit experiment, the phase difference between the two waves reaching at the location of the third dark fringe is

Statement I: In Young's experiment, the fringe width for dark fringes is different from that of white fringes. Statement II: In Young's doulbe-slit experiment, when the fringes are observed with a source of white light then only black and bright fringes are observed.
