A double slit experiment is shown in the figure.
Each slit has width W. A thin piece of glass of
thickness δ refractive index µ, is placed betweenone of the slits and the screen. The intensity atthe central point is measured as function ofthickness δ. For what values of δ is the intensity at C is minimum

A thin glass plate of thickness t and refractive index `mu` is inserted between screen and one of the slits in a young's experiment. If the intensity at the centre of the screen is I, what was the intensity at the same point prior to the introduction of the sheet.

One slit of a double slit experiment is covered by a thin glass plate of refractive index 1.4, and the other by a thin glass plate of the refractive index 1.7. The point on the screen where the central maximum fall before the glass plate was inserted, is now occupied by what had been the fifth bright fringe was seen before. Assume the plate have the same thickness t and wavelength of light 480 nm. Then find the value of t in `mum`.

A light of wavelength `6000 Å` shines on two narrow slits separeted by a distance 1.0 mm and illuminates a screen at a distance 1.5 m away. When one slit is covered by a thin glass plate of refractive index 1.8 and other slit by a thin glass plate of refractive index `mu`, the central maxima shifts by 0.1 rad. Both plates have the same thickness of 0.5 mm. The value of refractive index `mu` of the glass is
