PhotoElectric Effect

The phenomenon is studied in condensed matter physics, and solid state and quantum chemistry to draw inferences about the properties of atoms, molecules and solids. The effect has found use in electronic devices specialized for light detection and precisely timed electron emission. The experimental results Photoelectric effect experiment. Metals have a ‘sea’ of free electrons. It is these spare electrons which are able to be dislodged by passing photons, provided that the photon has sufficient energy. That said, some non-metals, mostly in the metalloid group, can exhibit weak photoelectric effects, If the energy of the inbound photons is high Before photoelectric effect, it was thought that light only has wave nature but this experiment confirmed its particle nature too, which was exactly proved afterwards that light has dual nature.

Photoelectric effect Explaining the experiments on the photoelectric effect. How these experiments led to the idea of light behaving as a particle of energy called a photon. Photoelectric effect: experiment showing light is also a particle. Energy comes in particle-like chunks- basics of quantum physics. (energy of one chunk depends on frequency, wave-like beam of light has MANY chunks, energy of beam is sum) Today: I. Understand the P.E. experiment and what results you would Many experiments show that light has the nature of waves. However, some experimental results are best explained by assuming that light also has the nature of particles. This experiment investigates the photoelectric effect, which can be understood in terms of the particle nature of light.

The photoelectric effect refers to the emission, or ejection, of electrons from the surface of, generally, a metal in response to incident light. Perform this experiment using a quartz tube, two zinc plates, cathode and anode plates, ammeter, key, a … View Photoelectric Effect Lab Report.docx from PHYS 400 at Longwood University.
