Find the ratio of intensities at the two points X and Y on a screen in Young's double slit experiment, where waves from the two source S_(1) and S_(2) have path difference of zero, and lambda//4 respectively.

In Young’s double slit experiment, the central bright fringe can be identified

Statement-1 : In Young’s experiment, the fringe width for dark fringes is same as that for white fringes. Statement-2 : In Young’s double slit experiment performed with a source of white light, only black and bright fringes are observed.

(a) In Young's double slit experiment, a monochromatic source of light S is kept equidistant from the slits S_(1) and S_(2) . Explain the information of dark and bright fringes on the screen. (b) A beam of light consisting of two wavelength, 650 nm and 520 nm, is used to obtain interference fringes in a Young's double - slit experiment. (i) Find the distance of the third bright fringe on the screen from the central maximum for wavelengths 650 nm. (ii) What is the least distance from the central maximum where the bright fringes due to both the wavelengths coincide ? Given: The seperation between the slits is 4 mm and the distance between the screen and plane of the slits is 1.2 m.

A parallel beam of light (lambda= 5000 Å) is incident at an angle theta=30^@ with the normal to the slit plane in a Young's double slit experiment. The intensity due to each slit is I_0. Point O is equidistant from S_1 and S_2 . The distance between slits is 1mm.
