Note-A-Rific: Wave-Particle Duality Einstein’s photon theory of light brought up a question that most physicists believed had been answered in the debates between Christian Huygens and Isaac Newton… is light a particle or a wave? In Physics 20 you discussed light as a wave… always. But now serious questions had been raised as to whether or not this was true. Before we decide if light is a wave or particle, let’s examine the properties of the photoelectric effect based on each. “Light is a Wave” To keep one variable a constant, we will assume that we are testing monochromatic light (one color, one frequency). A higher intensity of light (like a brighter bulb) means a higher amplitude of wave A higher amplitude means that the wave has more energy . We would expect that if light is a wave, as the intensity of the light increases more electrons with higher E k should be ejected. The frequency should not affect photoelectric effect, since it has nothing to do with the energy of the wave. Example
