WebbThe photoelectric effect is a phenomenon where irradiating a blue light on metal emits electrons from it. However, red light does not cause electron emission from metal no … WebbExperiments with the photoelectric effect show that for each metal, there is a minimum frequency, ν 0, below which light, no matter how intense, is incapable of ejecting electrons. 3) In the classical wave theory, the electron to be ejected from the metal surface would absorb energy from a wave as it impinges on the metal plate. Webb10 apr. 2024 · Therefore, the answer to the question of which phenomenon shows the particle nature of light is the photoelectric effect. Photoelectric Effect . In this phenomenon, when electromagnetic radiation (such as light) hits the material, the emission of electrons takes place.

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 ...
