A wave travelling in positive X-direction with \[A=0.2m\] has a velocity of 360 m/sec. if \[\lambda =60m,\] then correct expression for the wave is [CBSE PMT 2002; KCET 2003]

\[y=0.2\sin \,\left[ \pi \left( 6t-\frac{x}{60} \right) \right]\]

\[y=0.2\sin \,\left[ 2\pi \left( 6t+\frac{x}{60} \right) \right]\]

\[y=0.2\sin \,\left[ \pi \left( 6t+\frac{x}{60} \right) \right]\]

\[y=0.2\sin \,\left[ 2\pi \left( 6t-\frac{x}{60} \right) \right]\]

\[y=0.2\sin \,\left[ \pi \left( 6t-\frac{x}{60} \right) \right]\]
