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

Q
Q: In a double-slit experiment, if the distance to the screen is increased, what happens to the fringe separation?
Solution: Fringe separation is directly proportional to the distance from the slits to the screen (D), so increasing D increases the fringe separation.
Steps: 5
Step 1: Understand what fringe separation means. It is the distance between the bright or dark lines (fringes) on the screen in a double-slit experiment.
Step 2: Know that the distance from the slits to the screen is called D.
Step 3: Remember that fringe separation is directly related to this distance D.
Step 4: If you increase the distance D (make it larger), the fringe separation also increases.
Step 5: Therefore, when you increase the distance to the screen, the fringes will be spaced further apart.
