I was studying a book on QM and found out that the wave function for a free particle of completely undetermined position travelling in positive x direction is given by(adsbygoogle = window.adsbygoogle || []).push({});

e^(2(pi)i(kx - nt)) where n is the frequency

i have been trying a lot to derive it but till now i can't . Can any one help me
