Fringe width decreases
Fringe width increases
Fringe visibility decreases
Fringe pattern disappears
Increasing the distance from the slits to the screen increases the fringe width, as fringe width β is proportional to the distance.

Q
Q: If the distance from the slits to the screen in a double-slit experiment is increased, what happens to the fringe pattern? (2023)
Solution: Increasing the distance from the slits to the screen increases the fringe width, as fringe width β is proportional to the distance.
Steps: 5
Step 1: Understand what a double-slit experiment is. It involves light passing through two slits and creating a pattern of bright and dark lines (fringes) on a screen.
Step 2: Know that the distance from the slits to the screen is important. This distance affects how the light waves spread out.
Step 3: Realize that increasing the distance from the slits to the screen means the light waves have more space to spread out.
Step 4: Understand that as the light waves spread out more, the distance between the bright and dark lines (fringe width) increases.
Step 5: Conclude that increasing the distance from the slits to the screen results in wider fringes on the screen.
