Theory of the photoelectric effect
WebbThe Nobel Prize in Physics 1921 was awarded to Albert Einstein "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric … WebbThe photoelectric effect has three important characteristics that cannot be explained by classical physics: (1) the absence of a lag time, (2) the independence of the kinetic energy of photoelectrons on the intensity of incident radiation, and (3) the presence of a cut-off frequency. Let’s examine each of these characteristics.

Webb15 feb. 2024 · Sorted by: 1. In classical mechanics, we consider intensity to be a measure of energy (it certainly is but it doesn't work well with the photoelectric effect). A physicist who loves classical mechanics would expect electrons to be ejected at any intensity (if not immediately, after sufficient time). In reality, it was observed that shining ...

WebbEinstein noted that the photoelectric effect depended on the wavelength, and hence the frequency of the light. At too low a frequency, even intense light produced no electrons. However, once a certain frequency was reached, even … WebbThe photoelectric effect is the emission of electrons or other free carriers when light shines on a material. Electrons emitted in this way can be called photo electrons. This phenomenon is generally studied in electronic physics, as well as in fields of chemistry, such as quantum chemistry or electrochemistry.
