Question: What happens to the interference pattern if the two slits in a double-slit experiment are no longer coherent?

Options:

Correct Answer: The pattern disappears

Solution:

If the two slits are not coherent, the interference pattern will disappear as the waves will not maintain a constant phase relationship.

What happens to the interference pattern if the two slits in a double-slit experiment are no longer coherent?

Step 1: Understand what coherent means. Coherent waves have a constant phase relationship, meaning they stay in sync with each other.
Step 2: In a double-slit experiment, coherent light waves pass through two slits and create an interference pattern on a screen.
Step 3: If the two slits are not coherent, the waves coming from them will not stay in sync.
Step 4: Without a constant phase relationship, the waves will interfere randomly instead of creating a clear pattern.
Step 5: As a result, the interference pattern (the series of bright and dark spots) will disappear.

Coherence – Coherence refers to the constant phase relationship between waves, which is essential for producing a stable interference pattern.
Interference Pattern – An interference pattern is created when waves from two coherent sources overlap, resulting in regions of constructive and destructive interference.
