Hi, I was wondering what is the physical meaning of these integrals:(adsbygoogle = window.adsbygoogle || []).push({});

\begin{equation}

\int_{-\infty}^{\infty} \psi \psi^* dx = 0

\end{equation}

\begin{equation}

\int_{-\infty}^{\infty} \psi x \psi^* dx = 0

\end{equation}

\begin{equation}

\int_{-\infty}^{\infty} \psi p \psi^* dx = NA

\end{equation}

?
