A) \[y=0.2\sin \pi \left[ 6t+\frac{x}{60} \right]\]
B) \[y=0.2\sin \pi \left[ 6t-\frac{x}{60} \right]\]
C) \[y=0.2\sin 2\pi \left[ 6t-\frac{x}{60} \right]\]
D) \[y=0.2\sin 2\pi \left[ 6t+\frac{x}{60} \right]\]
Correct Answer: C
Solution :
Given \[a=0.2\] metre \[\upsilon =360\,m/s,\,\lambda =60\] metre Equations of transverse wave travelling along positive x-axis \[y=a\sin 2\pi \left[ \frac{t}{T}-\frac{x}{\lambda } \right]\] or \[y=a\sin 2\pi \left[ \frac{\upsilon }{\lambda }t-\frac{x}{\lambda } \right]\] \[y=0.2\sin 2\pi \left[ 6t-\frac{x}{60} \right]\]
