Homework Statement Electrons in atoms are known to have energies in the range of a few eV. Show that the uncertainty principle allows electrons of this energy to be confined in a region the size of an atom (0.1 nm) Homework Equations \Deltax\Deltap \geq h bar / 2 \DeltaE\Deltat \geq...

Awesome, thank you so much.

Homework Statement How does an electron get from an excited state (r = 4ao) to a ground state (r = ao) without being anywhere in between? Homework Equations The Attempt at a Solution My only attempt would be to say that it does exist between for a short time, and during that time it emits a...

Oh, so follow-up question: If the graviton exists, and if there is a material to block it, we would theoretically be able to defy gravity?

A big part of the theory of the standard model is that the major forces are mediated by the exchanging of elementary particles. So hypothetically, if we discovered some material that blocked the photon, for example, does this mean an object wrapped in this material would be unaffected by the...

This is my first post. My name is John. I'm an undergraduate Physics and Mechanical Engineering student and I'm still unsure of the types of jobs that could be available for me once I graduate. Particularly jobs prior to grad school. After graduating I'll have a Bachelor's degree in Physics from...
