An interference pattern can be observed due to the superposition of more than one of the following waves:
(A) \(y=a\sin(\omega t)\)
(B) \(y=a\sin(2\omega t)\)
(C) \(y=a\sin\left(\omega t-\phi\right)\)
(D) \(y=a\sin(3\omega t)\)
Identify the waves from the options given below:
1. (B) and (C) only 2. (B) and (D) only
3. (A) and (C) only 4. (A) and (B) only
