In a Young\'s double slit experiment, the central point on the screen is

In a Young\'s double slit experiment, the fringe width is found to be 0.4 mm. If the whole apparatus is immersed in water of refractive index 4/3 without disturbing the geometrical arrangement, the new fringe width will be

In double slit experiment, for light of which colour the fringe width will be minimum?

In Young\'s double slit interference pattern the fringe width

In Young\'s double slit experiment, the phase difference between the light waves reaching third bright fringe from the central fringe will be (λ = 6000Å)

In Young\'s double slit experiment, if the widths of the slits are in the ratio 4 : 9, the ratio of the intensity at maxima to the intensity at minima will be

In Young\'s double slit experiment when wavelength used is 6000 Å and the screen is 40 cm from the slits, the fringes are 0.012 cm wide. What is the distance between the slits

In two separate set-ups of the Young\'s double slit experiment, fringes of equal width are observed when lights of wavelength in the ratio 1 : 2 are used. If the ratio of the slit separation in the two cases is 2 : 1, the ratio of the distances between the plane of the slits and the screen in the two set-ups is

In an interference experiment, the spacing between successive maxima or minima is
(Where the symbols have usual meanings)

In Young\'s double slit experiment, a third slit is made in between the double slits. Then
