Yeah i believe that it was an increase in intensity will increase the emf produced. With increasing intensity, comes an increasing amount of photons. As long as the energy of the photons is greater than the energy required to release an electron, each photon will release one electron.
1 week to my physics trial which will either be NEAP, Independant or CSSA. Has any one completed any one of these exams. IF so how did it go? Any really hard high verb order questions?
