Current and intensity relation
WebEinstein concluded that increasing intensity increases current because more photons would be released and consequently more electrons and more current. Thus, when we talk about photoemission and Compton effect, we consider light as particle; but when we talk about diffraction, interference and polarization, we consider light as wave.
