Photoelectric Effect: Does Vibration Affect Threshold Frequency?

Click For Summary
SUMMARY

The discussion centers on the photoelectric effect, specifically examining whether the threshold frequency for electron emission decreases when the metal's particles are vibrating due to heating. Participants confirm that increased thermal energy can indeed lower the threshold frequency, facilitating electron emission at lower incident light frequencies. This conclusion is supported by the principles of quantum mechanics and the behavior of electrons in heated metals.

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 ?
