The equation of a wave is given as \[y=0.07\sin (12\pi x-3000\pi t)\]. Where \[x\] is in metre and \[t\] in sec, then the correct statement is [UPSEAT 2003]

• A.            \[\lambda =1/6m,\ v=250m/s\]                                       
• B.            \[a=0.07m,\ v=300m/s\]
• C.            \[n=1500,\ v=200m/s\]    
• D.            None
