Wavelength of light used is 5000 A˚.

In YDSE, find the thickness of glass slab (μ=1.5) which should be placed before the upper slit S1 so that the central maximum now lies at a point where 5th bright fringe was lying earlier (before inserting the slab). Wavelength of light used is 5000 A˚.

In YDSE In Young's double slit experiment the wavelength of light was changed from 7000Å to 3500 Å. While doubling the separation between the slits which of the following is not true for this experiment?
