Young's Double Slit Experiment- Fringe Width

In Young's double slit experiment the fringe width is 4mm .If the experiment is shifted to water of refractive index 4/3 the fringe width becomes (in mm)

In Young's double slit experiment the fringe width obtained is 0.6cm , when light of wavelength 4800 Å is used. If the disatance between the screen and the slit is reduced to half, what should be the wavelength of light used to obtain fringes 0.0045 m wide ?

In Young's double slit experiment, if the width of 4th bright firnge is 2xx10^(-2) cm then the width of 6 th bright fringe will be cm

If the frequency of the source is doubled in Young's double slit experiment, then fringe width (beta) will be –

A thin transparent sheet is placed in front of a slit in Young's double slit experiment. The fringe width will

In Young's double slit experiment, the fringe width with light of wavelength 6000 Ã… is 3 mm. The fringe width, when the wavelength of light is changed to 4000 Ã… is

In a Young's double-slit experiment the fringe width is 0.2mm . If the wavelength of light used is increased by 10% and the separation between the slits if also increased by 10%, the fringe width will be

In a Young's double slit experiment, the fringe width is found to be 0.4mm . 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 Young's double slit experiment, the fringe width obtained by a monochromatic light of wavelength 6000Å is 2 mm. I fthe apparatus is dipped into water of R.I. 1:33, then change in fringe width will be
