WebApr 5, 2024 · The correct answer is option 2) i.e. Intensity of light. CONCEPT:. Photoelectric effect: The photoelectric effect is a phenomenon where electrons are ejected from a metal surface when the light of sufficient frequency is incident on it. Einstein suggested that l ight behaved like a particle and that each particle of light had energy … WebThe photoelectric current (same as the rate of emission of electrons) is directly proportional to the intensity of light falling on the electrode. Note from the figure below that with increasing intensity, the current increases. …

In the photoemission process, when an electron within some material absorbs the energy of a photon and acquires more energy than its binding energy, it is likely to be ejected. If the photon energy is too low, the electron is unable to escape the material. Since …
WebThe experimental observation(s) below that require(s) a quantum explanation for the photoelectric effect a. b. 16. is that more photoelectrons are emitted when the light frequency increases. is that the maximum kinetic energy of the photoelectrons is related linearly to the frequency of the light. is that every metal surface has a work function, a … WebThe photoelectric effect was explained in 1905 by A. Einstein. Einstein reasoned that if Planck’s hypothesis about energy quanta was correct for describing the energy …
WebExplanation by Einstein of the Photoelectric Effect Einstein’s theory of photoelectric effect is based on the revolutionary idea of Planck that light was a particle. The energy transferred to every light particle, quanta or photon depends on the frequency (v) of light, shown by the photoelectric effect equation.
