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

(1) y=0.2sin2π6t+x60

(2) y=0.2sinπ6t+x60

(3) y=0.2sin2π6t-x60

(4) y=0.2sinπ6t-x60

(3) A wave travelling in positive x-direction may be represented as y=Asin2πλ(vtx). On putting values y=0.2sin2π60(360tx)y=0.2sin2π6tx60
