Photons and Electrons question

Postby Alexia_Vanegas_1G » Thu Sep 29, 2016 12:51 am

If the threshold energy for an electron to be removed from a metal is reached, is it the amount of energy or number of photons that removes an electron from the metal?

It is the amount of energy. One photon removes one electron, provided that the photon has reached the threshold energy.
