Questions & Step-by-Step Solutions
In a double-slit experiment, if the screen is moved further away from the slits, what effect does this have on the fringe spacing?
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: Know that fringe spacing refers to the distance between these bright or dark lines on the screen.
Step 3: Recognize that the distance from the slits to the screen can affect how far apart these fringes are.
Step 4: When the screen is moved further away from the slits, the light waves have more space to spread out.
Step 5: This spreading out of light waves causes the fringes to be farther apart, increasing the fringe spacing.
Step 6: Remember that fringe width is directly proportional to the distance from the slits, meaning as the distance increases, the fringe spacing also increases.
