Lab – The Photoelectric Effect – PhET simulation Name_____Score_____ Introduction: In 1905 Max Planck, a German theoretical physicists, proposed a mathematical solution to what was known as the ultraviolet catastrophe with regards to the emission of electromagnetic radiation from a blackbody. The Photoelectric Effect Simply stated, the Photoelectric Effect observes that metals emit electrons when shone upon with light particles, or photons. Conducting an experiment using a PhET Interactive Simulation, I was able to find out what exactly determines when electrons are emitted.

Key Concepts: Figure 3. Photoelectric effect. A graph of the kinetic energy of an ejected electron, KE e, versus the frequency of EM radiation impinging on a certain material.There is a threshold frequency below which no electrons are ejected, because the individual photon interacting with an individual electron has insufficient energy to break it away. Photoelectric Effect: Description Activity takes students through an exploration of the variables involved with the Photoelectric effect.

Especially the fact that light of large wavelengths has no effect at all even if it is extremely intensive, appeared mysterious for the scientists. There is a Phet simulation for the photoelectric effect.2 In Figure 1, ultraviolet light of 400 nm with 50% of its maximum intensity shines on a sodium metal cathode. Electrons are ejected with varying energy. The electrons ejected from the metal and collected on the anode. The electrons flow back to the cathode through a wire. In Figure 1 this 2020-01-23 · Furthermore, using the PhET simulation for the Photoelectric Effect selected for Copper (Cu) the results of our graph is in agreement with the simulation data (Sim. 1): Sim. 1.

This means that energy arrives in ‘lumps’ known as quanta. These lumps or packets of energy are called photons. This contradicts the long accepted wave model, where light is considered as an electromagnetic wave, with energy arriving continuously. The apparatus is reproduced in the PhET simulation entitled “Photoelectric Effect 1.10”. Open the PhET simulation and explore the simulation.
