Questions & Step-by-Step Solutions
In a double-slit experiment, if the distance between the screen and the slits is increased, what happens to the fringe separation?
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: Identify the key components: the slits (where light passes through) and the screen (where the pattern appears).
Step 3: Recognize that fringe separation refers to the distance between the bright or dark lines on the screen.
Step 4: Note that the distance from the slits to the screen can be changed. This is the distance we are focusing on.
Step 5: Understand the relationship: as the distance from the slits to the screen increases, the fringes spread out more, meaning the separation between them increases.
Step 6: Conclude that increasing the distance from the slits to the screen results in greater fringe separation.
