Questions & Step-by-Step Solutions
In a double-slit experiment, if the distance between the slits is doubled, what happens to the fringe separation on the screen?
Step 1: Understand the double-slit experiment. It involves light passing through two slits and creating a pattern of bright and dark lines (fringes) on a screen.
Step 2: Know that fringe separation is the distance between these bright or dark lines on the screen.
Step 3: Learn that fringe separation is affected by the distance between the slits. Specifically, it is inversely proportional to this distance.
Step 4: If the distance between the slits is doubled, it means the new distance is 2 times the original distance.
Step 5: Since fringe separation is inversely proportional to the distance between the slits, if the distance increases, the fringe separation decreases.
Step 6: Therefore, if the distance is doubled, the fringe separation becomes half of what it was before.
