A wave travelling in positive X-direction with A = 0.2 m has a velocity of 360 m/sec if $\lambda$ = 60 m, then correct expression for the wave is

• A

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

• B

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

• C

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

• D

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