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. The Phet Simulation of the photoelectric effect is a great way to engage students with the details of this modern physics concept. It is based on the experiments of Robert A. Millikan who proved Einstein’s perspective by experiment. It is also possible to demonstrate the photoelectric effect with a small neon bulb.

Se hela listan på en.wikipedia.org What is Photoelectric Effect Photoelectric effect is the emission of electrons when the light falls on a material. Here the concept of Photoelectric effect has been explained by changing the intensity of light and frequency of light. Different target metals have been used to analyse the photoelectric effect.

1. For Sodium, find or calculate the following: a. Threshold frequency. OR http://phet.colorado.edu/new/simulations/sims.php?sim=Photoelectric_Effect. • In the Photoelectric Effect Simulation: ▫ Set METAL to the unknown metal (?

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. (2) We will begin by exploring how the intensity of light affects the stopping voltage in the experiment.
