Five different waves travelling in the same direction are represented by: Choose the correct answer from the options given below for interference to take place:
- A (A) and (E), (A) and (D), (D) and (E)
- B (A) and (B), (B) and (C), (D) and (E)
- C (A) and (E), (B) and (E), (C) and (D)
- D (C) and (D), (B) and (D), (A) and (B)
Answer & Solution
Correct Answer
(D) (C) and (D), (B) and (D), (A) and (B)
Step-by-step Solution
Detailed explanation
Stable interference requires coherent sources, meaning the waves must have the same frequency (the same \(\omega\) value). Interference occurs only between pairs of waves whose mathematical representations share the identical coefficient of time \(t\) in their phase expressions.…
