Q: In a two-slit interference pattern, if the distance between the slits is increased, what happens to the fringe separation?

Solution: Increasing the distance between the slits (d) decreases the fringe separation, as fringe separation is inversely proportional to d.

Steps: 5

Step 1: Understand what a two-slit interference pattern is. It is a pattern created when light passes through two closely spaced slits and creates bright and dark spots on a screen.
Step 2: Identify the key terms. The distance between the slits is called 'd', and the distance between the bright or dark spots on the screen is called 'fringe separation'.
Step 3: Know the relationship between the distance between the slits (d) and fringe separation. Fringe separation is inversely proportional to the distance between the slits.
Step 4: Inverse proportionality means that if one value increases, the other value decreases. So, if the distance between the slits (d) increases, the fringe separation decreases.
Step 5: Conclude that increasing the distance between the slits results in closer fringe separation on the screen.
