Photoelectric effect wave or particle
WebLight has particle-like activity and this is proved through the photoelectric effect. The photoelectric effect is when photons, or packets of light, are shone on metal and electrons are ejected from the surface of that metal. If the frequency (or energy) of the photon hitting the metal is below a certain value, then no electron is ejected. WebMay 19, 2024 · Oxygen is used for aerobic respiration.
