B) the production of current by silicon solar cells when exposed to … WebSep 12, 2024 · Explain why the photoelectric effect cannot be explained by classical physics Describe how Einstein’s idea of a particle of radiation explains the photoelectric effect When a metal surface is exposed to a monochromatic electromagnetic wave of sufficiently short wavelength (or equivalently, above a threshold frequency), the incident …
WebThe photoelectric effect is a phenomenon where electrons are emitted from the metal surface when light of sufficient frequency is incident upon it. The concept of the … WebEinstein was able to use Planck's quantization hypothesis to explain the photoelectric effect. As indicated in Figure 6.2.2 a minimum energy of 2.0 eV is required to eject a photon off of potassium, and so red light would not work, while green and purple would. Figure 6.2.2: Potassium requires 2.0eV to eject an electron, and a photon of red ...
