Dual nature of radiation and matter

Dual nature of radiation and matter In this activity you will be able to visualize how light knocks electrons off a metal target and describe the photoelectric effect experiment. STEPS: • Open the browser and type “ in the address bar. • Change intensity of light and observe how the intensity of light will affect the photo electric current and the energy of electrons • By adjusting the value of wavelength and observe how the wavelength of light will affect the photo electric current and the energy of electrons • Adjust the value of voltage from the battery and analyse the effect of potential difference on the photoelectric current. • Change the material of the target and analyse how it will affect the current and the energy of electrons. • Study the photo electric current – voltage graph and Photo electric current - intensity graph obtained from this experiment. Note: Install Java application if it is not in your browser. You can download all the phet simulation and works in off line from colorado.edu/en/offline-access . * Pictures are indicative only. * If browser requires, allow Flash Player or Java Script to load the page.
