A) \[200\,\,m\]
B) \[100\,\,m\]
C) \[20\,\,m\]
D) \[10\,\,m\]
Correct Answer: A
Solution :
Key Idea: Compare the given wave equation with its similar standard wave equation. The standard wave equation is \[y=a\,\sin \,2\pi \left( \frac{t}{T}-\frac{x}{\lambda } \right)\] ?(1) Where \[a\] is amplitude, \[T\] is periodic time and \[\lambda \] is displacement. Given, equation is \[y=0.03\,\,\sin \,\,\pi \left( 2t-0.01x \right)\] ?(2) Comparing Eqs. (1) and (2), we get \[\frac{2}{\lambda }=0.01\] \[\Rightarrow \] \[\lambda =\frac{2}{0.01}=200\,m\]You need to login to perform this action.
