Question: In a double-slit experiment, if the distance between the slits is halved, what happens to the fringe separation on the screen?

Options:

Correct Answer: It doubles

Solution:

The fringe separation is inversely proportional to the distance between the slits; halving the distance doubles the fringe separation.

In a double-slit experiment, if the distance between the slits is halved, what happens to the fringe separation on the screen?

In a double-slit experiment, if the distance between the slits is halved, what happens to the fringe separation on the screen?

Step 1: Understand the double-slit experiment. It involves light passing through two slits and creating a pattern of bright and dark lines (fringes) on a screen.
Step 2: Know that the distance between the slits affects how far apart these fringes are on the screen.
Step 3: Learn that fringe separation is inversely proportional to the distance between the slits. This means if you change the distance between the slits, the fringe separation changes in the opposite way.
Step 4: If you halve the distance between the slits, you are making the distance smaller.
Step 5: Since the fringe separation is inversely proportional, halving the distance between the slits will double the fringe separation on the screen.

Interference Patterns – The phenomenon of light and other waves creating patterns of constructive and destructive interference, which is observed in the double-slit experiment.
Fringe Separation – The distance between adjacent bright or dark fringes on the screen, which is affected by the distance between the slits and the wavelength of the light used.
Proportional Relationships – Understanding how changes in one variable (distance between slits) affect another variable (fringe separation) in a proportional manner.
