WebbQuestion: 2. The photoelectric effect shows that a minimum amount of energy is needed to eject an electron from a piece of metal. This supports the idea of quantized energy because it shows that changes in the intensity of the light have an effect on the ejection of electrons from a metal. WebbPhotoelectric effect experiment apparatus. So if light is classical wave, predict that just puts energy into plate, heats up, get diode current voltage curve. 0 Voltage Also takes time to heat up. C t •Light on longer, heat more, e’s out faster = more current. •Color light does not matter, only intensity.
Webb20 okt. 2024 · The photoelectric effect is significant because it demonstrates that light has particle-like qualities. It established that we can consider light as photons (packets) of energy where one photon interacts w/ one electron and each photon must have sufficient energy to remove each electron. This is why, in the original photoelectric experiment ...
