Question
According to the document, which of the following path differences between two waves would lead to destructive interference?
Correct Answer
Option C is the correct answer.
Detailed Explanation
The document states that destructive interference occurs when the path difference is π/k, 3π/k, 5π/k, etc., which is equivalent to λ/2, 3λ/2, 5λ/2, etc. Options A, B, and D correspond to integral wavelengths (0, λ, 2λ), which result in constructive interference.
Hint
Recall the conditions for constructive and destructive interference in terms of wavelength (λ) or wave number (k).
