In a biprism expeirment the slit is illuminated with light of waveleght 6000Å. The distance between the slit and eye piece is 0.9 m. The virtual images of the slit s are formed 3 mm apart. The source is then replaced by another sources of light of wavelength 5400Å. The slit and biprims are not disturbed. The distance betwene the slit and eyepiece to get the same band width s before is 2 m

In a biprism expeirment to determine the wavelenght of light, the distance between slit and eyepiece is 1,. Wavelenght of light used is 5600Å. When a convex lens is kept at a distance of 30 cm from the slit, the distance of fourth the two images is 0.7 mm. The distance of fourth dark band from the central bright band is

In a biprism experiment, the fringe width is 0.4mm. The distance between the fourthh dark fringe and the sixth bright fringe is

In Young's double slit experiment wave length of light used is 5000 Å and distance between the slits is 2 mm, distance of screen from the slits is 1m. Find fringe width and also calculate the distance of 7^(th) dark fringe from central bright fringe.

In Yonung's double-slit experiment, two slits which are separated by 1.2 mm are illuminated with a monochromatic light of wavelength 6000 Å The interference pattern is observed on a screen placed at a distance of 1 m from the slits. Find the number of bright fringes formed over 1 cm width on the screen.

In Young's experiment the distance between two slits is d/3 and the distance between the screen and the slits is 3D. The number of fringes in 1/3 metre on the screen, formed by monochromatic light of wavelength 3lambda , will be:

In biprism experiment ,the distance between source and eyepiece is 1.2 m,the distance between two virtual sources is 0.84 mm. Then the wavelength of light used if eyepiece is to be moved transversely through a distance of 2. 799 cm to shift 30 fringes is

In a biprism experiment, the distance between the sit and the eyepiece is 1m and distance between the two coherent sources is 0.5 mm. If the wavelength of light used I 6000Å , then distance of the 10th bright and from the central bright band is
