Question: In a double-slit experiment, if the distance to the screen is increased, what happens to the interference pattern?

Options:

Correct Answer: Fringe width increases

Solution:

Increasing the distance to the screen increases the fringe width, as fringe width is proportional to the distance from the slits.

In a double-slit experiment, if the distance to the screen is increased, what happens to the interference pattern?

In a double-slit experiment, if the distance to the screen is increased, what happens to the interference pattern?

Step 1: Understand what a double-slit experiment is. It involves shining light through two narrow slits to create an interference pattern on a screen.
Step 2: Know that the interference pattern consists of bright and dark stripes called fringes.
Step 3: Recognize that the distance from the slits to the screen affects how spread out these fringes are.
Step 4: When you increase the distance to the screen, the fringes become wider apart.
Step 5: This means that the fringe width (the distance between two adjacent bright or dark stripes) increases.
Step 6: Conclude that increasing the distance to the screen results in a more spread-out interference pattern.

Interference Pattern – The pattern of light and dark bands created by the constructive and destructive interference of waves from the two slits.
Fringe Width – The distance between adjacent bright or dark fringes in the interference pattern, which is affected by the distance to the screen.
Double-Slit Experiment – A fundamental experiment in quantum mechanics demonstrating the wave-particle duality of light and matter.
