Photoelectric Effect: Does Vibration Affect Threshold Frequency?

AI Thread Summary
The discussion centers on the photoelectric effect and whether the threshold frequency for electron emission is affected by the vibration of metal particles. It is established that there is a minimum frequency required for electrons to be emitted, but the impact of particle vibration on this threshold frequency is questioned. Participants suggest that heating the metal may influence the emission process. The consensus indicates that while vibration could affect the emission, the fundamental threshold frequency remains tied to the material's properties. Overall, the relationship between particle vibration and threshold frequency is complex and warrants further exploration.

About a week ago in class, I was learning about the photoelectric effect. My teacher described it as the emission of electrons as a consequence of their absorption of energy from electromagnetic radiation, etc, but later on I had a doubt:
I know there's minimum frequency, for a given metal, the incident light must have in order for electrons to be emitted from matter, but would this threshold frequency decrease, if the metal's particles were vibrating, prior to the radiation of light - by heating it, for instance ?

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
