Minimum frequency needed to eject electrons

Postby Niveda_Tennety_1H » Thu Sep 29, 2016 2:08 pm

In photoelectric experiments, typically what part of the electromagnetic spectrum is the incoming light? I understand that UV light is typically used, but what is the minimum frequency needed to eject electrons, albeit poorly?

it depends on the metal

As work function increases does the ionization energy increase? So do metals with larger atomic radii have lower work functions?
