      What should be the  wave function φ=A expi(kx-ωt) , or φ=A expi(ωt-kx) in quantum mechanics. In many problem it is seen that both are correct but using these two equation we get different value for a quantum mechanical operator . As example first equation gives momentum operator as {\hat {p}}=i\hbar {\frac {\partial }{\partial x}} but second equation gives the value as positive. From this sense the first equation is right but why second is wrong?
