According to the experiments concerned with photoelectric effect, what would inrease the kinetic energy of electron ejected from a metal surface? Decreasing the wavelength of the light, drecreasing the frequency of the light or increasing the number of photons of light striking the surface? Please help me with this question, im trying to understand it but after reading so many different answers in wikipedia and any other online source i'm getting even more confused!

  1. If you will go to the wikipedia site below and scroll down the page, you will come to two sections that clearly tell you that increasing the frequency (decreasing the wavelength) increases the K. E. of the electrons. Scroll to Experimental Results of Photoelectric Emission (item # 4) and the section directly following "Mathematical Description" in which the formula is Kmax = hf - work function.
    Note that making f more will make Kmax more.
