Calculate the distance between the centers of `4^(th) and 7^(th)` bright fringes in an interference pattern produced in young's slit experiment. Give separation between the slits `=1.1xx10^(-3)`, wavelength of light used `=589.3 nm`, and distance of the screen from the double slit `=1.3m`.

Calculate the distance between 5^(th) and 15^(th) bright fringes in an interference pattern obtained by experiment due to narrow slits separated by 0.2mm and illuminated by light of wavelength 560mm . The distance between the slit and screen is 1m .

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 the Youngs double slit experiment, the separation between the slits is halved and the distance between the slits and the screen is doubled, the fringe width will be :

What is the nature of graph between fringe width and the distance between the slits of Youngs double slit experiment ?

A beam of light consisting of two wave lengths 4200 Å and 5600 Å is used to obtain interference fringes in Young's double slit experiment. The distance between the slits is 0.3 mm and the distance between the slits and the screen is 1.5 m. Compute the least distance of the point from the central maximum, where the bright fringes due to both the wavelengths coincide.

A beam of light consisting of two wavelengths 500 nm and 400 nm is used to obtain interference fringes in Young's double slit experiment. The distance between the slits is 0.3 mm and the distance between the slits and the screen is 1.5 m. Compute the least distance of the point from the central maximum, where the bright fringes due to both the wavelengths coincide.
