Question: What happens to the fringe pattern in Young\'s double-slit experiment if the distance to the screen is halved?

Options:

Correct Answer: Fringe width decreases

Solution:

Fringe width (β) is inversely proportional to the distance to the screen (D). If D is halved, the fringe width decreases.

What happens to the fringe pattern in Young's double-slit experiment if the distance to the screen is halved?

Step 1: Understand that in Young's double-slit experiment, light passes through two slits and creates a pattern of bright and dark lines called fringes on a screen.
Step 2: Know that the distance from the slits to the screen is called 'D'.
Step 3: Learn that the width of the fringes (the distance between bright lines) is called 'fringe width' (β).
Step 4: Remember that fringe width (β) is inversely proportional to the distance to the screen (D). This means that if D gets smaller, β gets smaller too.
Step 5: If the distance to the screen (D) is halved, the fringe width (β) will decrease, making the fringes closer together.
