SUMMARY
The discussion focuses on computing the complex conjugate of the expectation value of momentum, denoted as
, using equation 1.35:
=∫ψ*(h/i)∂/∂x ψ dx. The correct approach to find the complex conjugate involves changing the sign of the imaginary unit and switching the wavefunction's conjugate, resulting in
=∫ψ(-h/i)∂/∂x ψ* dx. The participants confirm that the expectation value
is real, as it equals its own complex conjugate,
=
*.
