A) 200 m
B) 100 m
C) 20 m
D) 10 m
Correct Answer: A
Solution :
[a] \[y=0.03\,\,\sin \pi (2t-0.01x)\] is equation of a progressive wave. Comparing it with the standard form of equation \[y=a\,\sin \,(\omega \,t-kx)\] \[\omega =2\,\pi \,;\]\[k=0.01\,\,\pi \] \[k=\frac{2\pi }{\lambda }=0.01\pi \] \[\Rightarrow \]\[\lambda =\frac{2}{0.01}=200\,\,m.\]You need to login to perform this action.
