A) 20 cm
B) 10 cm
C) 40 cm
D) 30 cm
Correct Answer: D
Solution :
On comparing the given equation with standard equation \[y=2a\sin \frac{2\pi x}{\lambda }.\cos \frac{2\pi vt}{\lambda }\] we get, \[\frac{2\pi }{\lambda }=\frac{\pi }{20}\] \[\Rightarrow \] \[\lambda =40\] Separation between two consecutive nodes \[=\frac{\lambda }{2}=\frac{40}{2}=20\,cm\]You need to login to perform this action.
