1. ### I Intuition for Rayleigh Scattering

Thanks! Sorry for the slow reply - I've been away from a connection for a while. I guess as Bystander says it does make intuitive sense that you should have a factor of volume squared for scattering of two particles. But in that case why should the photon be seen as having the same volume as the...
2. ### I Intuition for Rayleigh Scattering

Is there some way to - from an intuition standpoint - justify the fact that there should be a factor of $a^{6}$, (where $a$ is the particle diameter) in the Rayleigh Scattering formula? I've seen a few sources hint that there should be. I can follow the derivation from e.g a Lorentz atom...
3. ### I Energy levels generally invariant under fixed V, changing T

Why is is true that for a given system, if I fix the volume and increase the temperature, you'd expect the occupancy of the energy levels to change, but not the levels themselves? Can I think of this in terms of the fact that the boundary conditions for the solution of the TISE are fixed, such...
4. ### I Confusion With Derivation of Fresnel Equations

Okay, so I'm working with the diagrams above. $i$ denotes incident, $r$ reflected, and $t$ transmitted. -We're working in two HIL dielectrics. Incoming and outgoing waves are of form $Aexp[i(\vec{k}\cdot\vec{r}- \omega t)$. As I understand it, Maxwell's equations give four boundary...
5. ### For what time does an electron move after current turned off?

Thanks. What are [tex] u(t) [\tex] and [tex] v(t) [\tex] please?
6. ### For what time does an electron move after current turned off?

Hi, Can someone point me in the right direction in terms of calculating the length of time an electron in a wire would continue to move after the current is turned off? Can we use the drift velocity in some way? Thanks!
