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

Solution: Increasing the distance between the slits decreases the fringe width, making the pattern narrower.

Steps: 5

Step 1: Understand the double-slit experiment. It involves light passing through two slits and creating an interference pattern on a screen.
Step 2: Know what fringe width is. Fringe width is the distance between the bright or dark lines in the interference pattern.
Step 3: Recognize that the distance between the slits affects the interference pattern. If the slits are closer together, the fringes are wider apart.
Step 4: If you increase the distance between the slits, the fringes become narrower. This means the bright and dark lines are closer together.
Step 5: Conclude that increasing the distance between the slits decreases the fringe width, making the pattern narrower.
