A) \[\lambda =2\pi \times {{10}^{-2}}\,m\]
B) \[\lambda ={{10}^{-3}}\,m\]
C) \[n=\frac{{{10}^{3}}}{2\pi }Hz\]
D) \[n={{10}^{4}}\,Hz\]
Correct Answer: A
Solution :
\[{{v}_{\max }}=a\omega =\frac{v}{10}=\frac{10}{10}=\]m/sec \[\Rightarrow \]\[a\omega =a\times 2\pi n=1\]\[\Rightarrow \]\[n=\frac{{{10}^{3}}}{2\pi }\] \[(\because \,\,a={{10}^{-3}}\,m)\] Since \[v=n\lambda \Rightarrow \lambda =\frac{v}{n}=\frac{10}{{{10}^{3}}/2\pi }=2\pi \times {{10}^{-2}}\]\[m\]You need to login to perform this action.
