In double-slit diffraction, what is the effect of increasing the distance between the slits on the fringe width?

In double-slit diffraction, what is the effect of increasing the distance between the slits on the fringe width?

Step 1: Understand what double-slit diffraction is. It is a pattern created when light passes through two closely spaced slits.
Step 2: Know that fringe width is the distance between bright or dark spots in the diffraction pattern.
Step 3: Recognize that the distance between the slits affects how light waves spread out after passing through them.
Step 4: Realize that increasing the distance between the slits causes the light waves to spread out more.
Step 5: Understand that as the light waves spread out more, the angle of diffraction increases.
Step 6: Conclude that a larger angle of diffraction means the bright and dark spots (fringes) are farther apart, increasing the fringe width.
