1.	In y=Asin(wt-kx), x is the displacement and t is the time taken, then the dimensional formula of w is
Answer» tion:In the given equation y=Asin(ωt−kx)SINCE, trigonometric function is a dimensionless quantity. So, (ωt−kx)is also dimensionless quantity.So,(ωt−kx)=1ωt=1[ω]= 1/ [T ] =[T]−1kx=1[K]= 1/[L] =[L] −1
