Question

Interference pattern can be observed due to superposition of the following waves: A. $y=a \sin \omega t$ B. $y=a \sin 2 \omega t$ C. $y=a \sin (\omega t-\phi)$ D. $y=a \sin 3 \omega t$ Choose the correct answer from the options given below.

Professor PC Thomas Classes · Answer

(c) : For obtaining interference pattern, the two superimposing waves should be of same frequency. It is clear from the given options that waves in option A and C have same frequency, so they will superimpose and give interference pattern.
