Question

Sustained interference is caused by the superposition of two waves coming from two coherent sources. (T/F)

Hint:

For sustained interference patterns, the sources must be coherent, meaning they must have a constant phase relationship.

Answer 1

Step 1: Understanding the concept.
Sustained interference patterns occur when two coherent sources produce waves that superpose constructively and destructively, creating a stable pattern. Coherence is essential for sustained interference.
Step 2: Analyzing the statement.
The statement is True, as sustained interference requires two coherent sources to produce a stable and observable interference pattern.
Step 3: Conclusion.
The correct answer is True, as sustained interference is indeed caused by the superposition of two waves from coherent sources.
