In Young's double slit experiment, fringes of certain width are produced on the screen kept at a certain distance from the slits. When the screen is moved away from the slits by 0.1m, fringe width increases by `6xx10^(-5)m`. The separation between the slits is 1 mm. calculate the wavelength of the light used.

In Young's double slit experiment , fringes of width beta are produced on a screen kept at a distance of 1 m from the slit . When the screen is moved away by 5 xx 10^(-2) m , fringe width changes by 3 xx 10^(-5) m . The separation between the slits is 1 xx 10^(-3) m . The wavelength of the light used is ....nm

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 :

In Young's double slit experiment the slits are separated by 0.28mm and the screen is placed at a distance of 1.4m away from the slits. The distance between the central bright fringe and the fifth dark fringe is measured to be 1.35cm . Calculate the wavelength of the light used. Also find the fridge width if the screen is moved towards the slits by 0.4m , for the same experimental set up.
