Hamiltonian operator commutes with the linear momentum operator(adsbygoogle = window.adsbygoogle || []).push({});

and for a particle in the box its wavefunction is Nsin(nπx/a) , N is the normalization constant

But I found this wavefuntion is not a eigenfuntion for the momentum operator, why? Isn't the two operators commut with each other?
