A) 330 Hz
B) 342 Hz
C) 365 Hz
D) 660 Hz
Correct Answer: A
Solution :
Given that y \[y=15\,\sin \,(660\pi t-0.02\,\pi x)\] Comparing with general equation of progressive wave, we get \[y=(x,t)=A\sin \left( \frac{2\pi }{T}t-\frac{2\pi }{\lambda }x \right)\] \[\therefore \] \[\frac{2\pi }{T}=660\pi \]or \[\frac{1}{T}=330\]pr \[v=330\,\text{Hz}\]You need to login to perform this action.
