In a double-slit experiment, if the screen distance is increased, what happens to the fringe separation?
Fringe separation increases
Fringe separation decreases
Fringe separation remains the same
Fringe separation becomes zero
Fringe separation is directly proportional to the distance from the slits to the screen (D), hence it increases.

Q: In a double-slit experiment, if the screen distance is increased, what happens to the fringe separation?
Solution: Fringe separation is directly proportional to the distance from the slits to the screen (D), hence it increases.
Steps: 4
Step 1: Understand what the 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: Identify the key components: the distance from the slits to the screen is called 'D', and the distance between the bright or dark lines is called 'fringe separation'.
Step 3: Recognize the relationship: fringe separation increases when the distance 'D' increases. This means that if you move the screen further away from the slits, the fringes will spread out more.
Step 4: Conclude that increasing the screen distance results in larger fringe separation.
