In a photoelectric effect testing where the purpose is to investigate the relationship of the kinetic energy of the emitted electrons to the brightness intensity, rate of energy flow per unit area as well as to the color wavelength or frequency of the incident light, we utilize mercury light to find the Vo for Blue, Green, Yellow, Violet & ultraviolet. If we exchanged the mercury light with an ordinary white light source what could we expect to get for Vo?
