Hi, I have the dilema that my course is a distance learning degree (open university) so I am balancing learning with my work and being in the sticks reduces the time I can get to any library. Currently my local uni library is closed to outsiders until the exam period finishes (conveniently after...
Hi, sorry for replying late, I am a 3rd year undergrad of Physics, and I am struggling to make sense of the vector spaces and usiing dirac notation as before I covered wave mechanics using Schrodingers eqn. I have looked at harmonic oscillators, expectation value, uncertainty etc from the...
Thanks, I have seen your recommendations, not sure how to see your edits exactly! I am quite new to this forum and it is my first post. So I am basing my working off of these rules for hermitian operators /BUT/ do they still work when I principely have a sandwich int...? Because when the...
Yeah oops It should be C, I am aware of the relation for Ekin - square of momentum and the factor 1 / 2m. How does the factor come about in the instance of <Px Psi | Px Psi>??
Homework Statement
Using Dirac Notation prove for the Hermitian operator B acting on a state vector |ψ>, which represents a bound particle in a 1-d potential well - that the expectation value is <C^2> = <Cψ|Cψ>.
Include each step in your reasoning. Finally use the result to show the...
