What happens to the fringe pattern if in the path of one of the slits a glass plate which absorbs 50% energy is interposed?

What happens to the interference pattern when one of the slits is closed?

What happens to the interference pattern,when one of the slits is closed?

What happens to the fringe pattern when the Youngs double slit experiment is performed in water instead of air ?

What happens to the fringe pattern when the Young's double slit experiment is performed in water intesed of air ?

What happens to fringe width, whne the separation between the slits as well as distance of the screen from the slit are halved?

Interference pattern with Young's double slits 1.5mm apart are formed on a screen at a distance 1.5m from the plane of slits. In the path of the beam of one of the slits, a transparent film of 10 micron thickness and of refractive index 1.6 is interposed while in the path of the beam from the older slit a transparent film of 15 micron thickness and of refractive index 1.2 is interposed. Find the displacement of the fringe patten.

In Young's double slit experiment, the fringes are displaced by a distance x when a glass plate of one refractive index 1.5 is introduced in the path of one of the beams. When this plate in replaced by another plate of the same thickness, the shift of fringes is (3/2)x. The refractive index of the second plate is
