Question: What is the effect of increasing the distance between the slits in a double-slit experiment on the fringe separation?

Options:

Correct Answer: Decreases fringe separation

Solution:

Increasing the distance between the slits decreases the fringe separation as fringe width is inversely proportional to the slit separation.

What is the effect of increasing the distance between the slits in a double-slit experiment on the fringe separation?

Step 1: Understand what a double-slit experiment is. It involves light passing through two narrow slits and creating a pattern of bright and dark spots on a screen.
Step 2: Know what fringe separation means. Fringe separation is the distance between the bright or dark spots in the pattern.
Step 3: Learn about slit separation. This is the distance between the two slits in the experiment.
Step 4: Recognize the relationship between slit separation and fringe separation. When the distance between the slits increases, the fringe separation decreases.
Step 5: Remember that fringe width is inversely proportional to slit separation. This means that if you make the slits farther apart, the fringes will be closer together.
