Post- Module Assessment #24
In photoelectric experiments, typically what part of the electromagnetic spectrum is the incoming light? Also, to better my understanding, why does the light typically lie in a specific part of the spectrum. For example, why can't visible light eject electrons? Is it because the wavelength in the visible spectrum is simply too long?

I think UV light is typically used because it has sufficient energy (higher frequency than visible light) to eject e-.

Thank you, that makes sense. Do you know why gamma rays wouldn't work then, since they have an even higher freq?

I think gamma rays would work, but UV light is just easier to use. I'm not completely sure though
