similarly, how to prove that a wave given as A.exp[i (wt + kx) ] is moving in negative x direction ?

Thanks a lot

Consider a point with fixed displacement y. If t increases, x must increase also to keep y constant.

But in y = Aexp[i(wt + kx)] to keep y constant as time t increses then x must decrease.
