⟨x⟩ = L/2

: The time-independent Schrödinger equation for a free particle is given by:

: Show that the commutation relation between the position and momentum operators is given by: Introductory Quantum Mechanics Liboff 4th Edition Solutions

[x, p] = iℏ

Evaluating the commutator, we obtain:

[x, p] = xp − px

which is the energy of a free particle.

: Find the expectation value of the position operator for a particle in a one-dimensional box.
