In Young's double slit experiment a mica plate of refractive index `mu` is introduced in the path of light coming from one of the slit . If the central bright frige gets shifted to the point originally occupied by the fourth bright fringe, then the thickness of the mica plate will be ( symbols have their usual meaning )

In Young's experiment, if a slab of mica of refractive index mu and thickness of t is introduced in the path of light from one of the slits, then number of fringes formed on the screen will –

In a young's double slit experiment, one of the slits is covered by a glass sheet of thickness 2.5xx10^(-5) m. Due to this, the position of the central bright fringe is shifted to position originally occupied by the 30th bright fringe. If lamda=5000 Å, then the refractive index of glass is

In a double-slit experiment, fringes are produced using light of wavelength 4800A^(@) . One slit is covered by a thin plate of glass of refractive index 1.4 and the other slit by another plate of glass of double thickness and of refractive index 1.7. On doing so, the central bright fringe shifts to a position originally occupied by the fifth bright fringe from the centre. find the thickness of the glass plates.

In a double-slit experiment, fringes are produced using light of wavelength 4800A^(@) . One slit is covered by a thin plate of glass of refractive index 1.4 and the other slit by another plate of glass of same thickness and of refractive index 1.7. On doing so, the central bright fringe shifts to a position originally occupied by the fifth bright fringe from the centre. find the thickness of the glass plates.

I Young.s double slit experiment a mica plate of thickness .t. and refractive .mu. is introduced in one of the interfering beams. Then the central fringe will be displaced through (d= distance between the slits, D= distance between the slits and the screen)

In Young's experiment if mica disc of thickness t and refractive index is placed in the path of one ray coming out of slit, fringes will move ...... distance on the screen
