In a Young's double slit experiment, two wavelengths of 500nm and 700 nm were used. What is the minimum distance from the central maximum where their maxima's coincide again? (Take D/d=1000) . Symbols have their usual meanings

To prodce inteference fringes in Young' s double slit experiment light consisting of two wavelengths of 6500 Å and 5200 Å is used. (i) Determine the distance of the third maxima from the central maxima for light of wavelength 6500 Å . (ii) At what minimum distance from the central maxima will the bright points (maxima) for two waves superpose? Given that distance between the two slits is 2 mm and the distance of the screen from the plane of the slits is 120 cm.

A beam of light consisting of two wavelengths 800 nm and 600 nm is used to obtain the interference fringes in a Young's double slit experiment on a screen placed 1.4m away. If the two slits are separated by 0.28 mm, calulate the least distance from the central bright maximum where the bright fringes of the two wavelengths coinside.

In Young's double slit experiment the wavelenght of light used is 5000 Å the slit -separation is 0.2 mm and the screen is placed at a distance 200 cm from the slits . Central maxima is at x=0 . If the central maxima is assumed as the zeroth bright band then what will be the distance of the third bright band?

In Young's double slit experiment the distance between the two slits is d and wavelength of the light used is lambda . The angular width of the fringe

In a Young's double slit experiment slits are separated by 0.5mm and the screen is placed 150 cm away. A beam of light consisting of two wavelength 650 nm and 520 nm is used to obtain interference fringes on the screen. The least distance from the common central maximum to the point where the bright due to both the wavelengths coincide is

In Young' s double slit experiment, two monochromatic light of wavelengths 650 nm and 520 nm are used to form an interference pattern . Seprsation between the two slits is 2xx 10^(-3) m and screen is 1.20 m away from the slits. At what minimum distance apart from the central maxima, bright fringes due to both the waves will be overlapped?

In Young's double slit experiment the coherent sources are 1.5 mm apart and the fringes are obtained on a screen at a distance 2.5 m from the plane of the sources. If the sources is illuminated with a light of 589.3 nm wavelength , find the number of fringes in the interference pattern thus formed on the screen. Total length of the fringes are 4.9 xx 10 ^(-3) m.
