WebFeb 20, 2024 · For now, we will use the photon concept to explain the photoelectric effect, much as Einstein did. Figure 29.2. 2: An EM wave of frequency f is composed of photons, or individual quanta of EM radiation. The energy of each photon is E = h f, where h is Planck’s constant and f is the frequency of the EM radiation. WebApr 8, 2024 · Minimum conditions for Photoelectric Effect: Threshold Frequency: It is the minimum frequency of the incident light or radiation that will produce a photoelectric effect. Threshold wavelength: During the emission of electrons, a metal surface corresponding to the greatest wavelength to incident light is known as threshold wavelength.
