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