Q: What is the effect of increasing the distance between the slits in a double-slit experiment on the interference pattern?
Solution: Increasing the distance between the slits decreases the fringe width, making the fringes closer together.
Steps: 5
Step 1: Understand the double-slit experiment. It involves shining light through two closely spaced slits to create an interference pattern on a screen.
Step 2: Know what fringe width is. Fringe width is the distance between two bright or dark spots in the interference pattern.
Step 3: Recognize that the distance between the slits affects the interference pattern. If the slits are farther apart, the light waves spread out less.
Step 4: Realize that increasing the distance between the slits means the light waves will interfere more closely together.
Step 5: Conclude that as the distance between the slits increases, the fringe width decreases, making the bright and dark spots closer together.
