## Homework Statement

Here is another True or False question from the same practice test.

Since the expectation of the momentum operator <

**p**>=<n|

**p**n> is zero for an energy eigen state of the harmonic oscillator, a measurement of the momentum will give zero every time (True or False).

## Homework Equations

N/A

## The Attempt at a Solution

This question sounds very false to me, since an expectation value implies a probability and not an absolute. However, I'm thinking it might be a trick question...

Thanks!
