What happens to the interference fringes when the distance between the two coherent sources is decreased?

In Young’s double slit experiment, the distance of screen is increased 4 times and distance between two coherent sources is reduced to half. The fringe width will

What is the distance between two base pairs in DNA?

In Young.s double slit experiment, slits are separated by 2 mm and the screen is placed at a distance of 1.2 m from the slits. Light consisting of two wavelengths 6500Å and 5200Å are used to obtain interference fringes. Then the separation between the fourth bright fringes of two different patterns produced by the two wavelengths is

What is the nature of graph between fringe width and the distance between the slits of Youngs double slit experiment ?

What happens at the synpse between two neurons ?

What happens to the effective resistance when two resistors are connected in series?
