1.3: Photoelectric Effect Explained with Quantum Hypothesis

WebIt's the emission of electrons from a metal that has absorbed electromagnetic radiation like light over a certain frequency. A particle of light is called a photon, and when a photon has enough energy, it can actually knock an electron free. What happens is that the photon collides with the metal surface, hitting an electron. Webequations. Einstein and Millikan described the photoelectric effect using a formula (in contemporary notation) that relates the maximum kinetic energy ( Kmax) of the photoelectrons to the frequency of the absorbed photons ( f) and the threshold frequency ( f0) of the photoemissive surface. Kmax = h ( f − f0) how do you say job title in spanish phone number to the food stamp office

"WebBecause the electrons can only absorb one photon of a given wavelength. Electrons can ONLY absorb photons of very specific wavelengths and no others. And they CANNOT absorb two or three photons that add up to the required wavelength. When dealing with things in the quantum realm, our "intuitive sense" will fail us.
