In Young's double slit experiment slits are separated by 2 mm and the screen is placed at a distance of1.2 m from the slits. Light consisting of two wavelengths `6500Å` and `5200Å` are used to obtain interference fringes.
The the separation between the fourth bright fringes the two wavelength is

In Young.s double slit experiment, slits are separated by 2 mm and the screen is placed at a distance of 1.2 m from the slits. Light consisting of two wavelengths 6500Å and 5200Å are used to obtain interference fringes. Then the separation between the fourth bright fringes of two different patterns produced by the two wavelengths is

In a Young's double slit experiment two slits are separated by 2 mm and the screen is placed one meter away. When a light of wavelength 500 nm is used, the fringe separation will be:

In Young's double slit experiment, the slits are 0.5mm apart and interference pattern is observed on a screen placed at a distance of 1.0m from the plane containg the slits. If wavelength of the incident light is 6000Å , then the separation between the third bright fringe and the central maxima is

In the Young's double slit experiment, the spacing between two slits is 0.1mm . If the screen is kept at a distance of 1.0m from the slits and the wavelength of ligth is 5000Å , then the fringe width is

In the Young's double slit experiment, the spacing between two slits is 0.1mm . If the screen is kept at a distance of 1.0m from the slits and the wavelength of ligth is 5000Å , then the fringe width is

In Young's double slit experiment, slit separation is 0.6 mm and the separation between slit and screen is 1.2m . The angular width is (the wavelength of light used is 4800Å )

In Young's double slit experiment the slit separation is d = 1 mm and the screen is at a distance D = 1m. Monochromatic light of wavelength lambda = 5000A^@ is used. Then the distance of the third dark form the central bright fringe is
