A) 64 cm/s, in - x direction
B) 32 cm/s, in - x direction
C) 32 cm/s, in + x direction
D) 64 cm/s, in + x direction
Correct Answer: D
Solution :
\[Y=4\,\sin \,\left( 4\pi t-\frac{\pi \,x}{16} \right)\] where, \[\omega =4\pi \]and \[k=\frac{2\pi }{\lambda }=\frac{\pi }{16}\] \[\Rightarrow \] \[v=\frac{\omega }{k}=\]64 cm/s along + x direction.You need to login to perform this action.
