A) \[10{{\sec }^{-1}}\]
B) \[2\,{{\sec }^{-1}}\]
C) \[1\,{{\sec }^{-1}}\]
D) \[0.01\,{{\sec }^{-1}}\]
Correct Answer: C
Solution :
Comparing with the standard equation, \[y=A\sin \frac{2\pi }{\lambda }(vt-x)\], we have \[v=200\]\[cm/\sec \], \[\lambda =200\]\[cm\,;\]\[\therefore \]\[n=\frac{v}{\lambda }=1\]\[{{\sec }^{-1}}\]
