Timeframes of Electron Excitation: Phosphorescence Excluded

AI Thread Summary
The discussion focuses on the timeframes of electron excitation, specifically excluding phosphorescence. It highlights that an excited electron can return to its ground state directly or through an intermediate energy level, as seen in ruby LASERs. The key question raised is what factors influence the duration of this return process. One participant suggests that the timing may be indeterminate. The conversation emphasizes the complexities of electron behavior in excited states.

Excluding the process of Phosphorescence, an electron in an excited state will return directly or with a intermediate step to its grown state (like in a ruby LASER before the stimulated emission, where first absorbs a green photon, drops to an intermediary energy level and then emits a red photon by stimulation). But what determines the time it takes for this to happen?
Thank you

Thread 'Inducing EMF Through a Coil: Understanding Flux'

Thank you for reading my post. I can understand why a change in magnetic flux through a conducting surface would induce an emf, but how does this work when inducing an emf through a coil? How does the flux through the empty space between the wires have an effect on the electrons in the wire itself? In the image below is a coil with a magnetic field going through the space between the wires but not necessarily through the wires themselves. Thank you.

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility . Calculate the force on a point charge situated a distance above the origin. In the page 196, in the first paragraph, the author argues as follows ...
