In young's experiment, fringes are obtained on a screen placed at a distance of 75 cm from the slits. If the separation of the narrow slits is doubled, the fringe width is decreased.
Through what distance the screen should be moved, in order to restore the spacing of the fringes?

In Young's experiment, interference fringes are obtained on a screen placed at some distance from the slits. When the screen is moved towards the slits by 5xx10^(-2)m , the fringe width is changed by 3.5xx10^(-5)m . If the separation between the slits is 1 mm, then th wavelength of light used is

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, if the distance between the slits is halved and the distance between the slits and the screen is doubled, the fringe width becomes

In young's double slit experiment with monochromic light, fringes are obtained on a screen placed at some distance from the plane of slits. If the screen is moved by 5 cm towards the slits, then the change in fringe width is 30mum if the distance between the slits is 1mm, then calculate wavelength of the light used.
