Calculate the fringe width of the interference pattern. Given wavelength of light used `=678` nm, distance between the slits `=0.35 `mm, distance between the screen and the double slit = 1 m.

In Young's doubles slit experiment for producing interference pattern the fringe width depends on i) wave length ii) distance between the two slits iii) distance between the screen and the slits iv) distance between source and the slits

(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.

Monochromatic light from a narrow slit illuminates two parallel slits producing an interference pattern on a screen. The separation between the two slits is now doubled and the distance between the screen and the slits is reduced to half. The fringe width

Light of wavelength 6000 overset(@)A is used to obtain interference fringe of width 6 mm in a young's double slit experiment. Calculate the wavelength of light required to obtain fringe of width 4 mm if the distance between the screen and slits is reduced to half of its initial value.

In Young's double slit experiment, the slits are 3 mm apart. The wavelength of light used is 5000 Å and the distance between the slits and the screen is 90 cm. The fringe width in mm is
