Chapter 11, Problem 11.25E

Interpretation Introduction

Interpretation:

The value of $\langle x^2\rangle$ for ${\Psi }_0$ of a harmonic oscillator is to be calculated. Whether the obtained value is similar to the expected value is to be predicted.

Concept introduction:

In quantum mechanics, the wavefunction is given by $\Psi$. The wavefunction contains all the information about the state of the system. The wavefunction is the function of the coordinates of particles and time. The square of the probability function, ${\left|\Psi \right|}^2$, relates to the probability density.
