A standing wave is represented by

Y=Asin(100t)cos(0.01x)

where Y and A are in millimetre, t is in seconds and x is in metre. The velocity of wave is 

(1) 104 m/s

(2) 1 m/s

(3) 10–4 m/s

(4) Not derivable from above data

(1) By comparing given equation with y=asin(ωt)coskx

v=ωk=1000.01=104 m/s
