Physics - Wave on String Question with Solution | TestHub

Given that y=15sin (660 πt-0.02πx)

Comparing with general equation of progressive wave, we get

$y=\left(x,t\right)=a\sin \left(\frac{2\pi }{T}t-\frac{2\pi }{\lambda }x\right)$

$\therefore \frac{2\pi }{T}=660\pi$

$or \frac{1}{T}=330 or v=330 Hz$
