A) 0.04
B) 0.01
C) 1
D) 5
Correct Answer: A
Solution :
The given equation is \[y=5\,\sin \frac{\pi }{2}(100\,t-x)\] ?(i) Comparing Eq. (i) with standard wave equation, given by \[y=A\text{ sin}\left( \omega t-kx \right)\] ...(ii) we have \[\omega =\frac{100\,\pi }{2}=50\,\pi \] \[\Rightarrow \] \[\frac{2\pi }{T}=50\,\pi \] \[\Rightarrow \] \[T=\frac{2\pi }{50\pi }=0.04\,s\]You need to login to perform this action.
