Questions & Step-by-Step Solutions
In a double-slit experiment, if the distance between the slits is increased, what happens to the number of visible fringes on the screen?
Step 1: Understand what a double-slit experiment is. It involves shining light through two closely spaced slits to create an interference pattern on a screen.
Step 2: Know that the interference pattern consists of bright and dark stripes called fringes.
Step 3: Recognize that the distance between the slits affects how the light waves interact with each other.
Step 4: When the distance between the slits is increased, the fringe width (the distance between adjacent bright or dark fringes) decreases.
Step 5: Since the fringe width is smaller, more fringes can fit within the same distance on the screen.
Step 6: Therefore, increasing the distance between the slits results in more visible fringes on the screen.
