Gold leaf photoelectric effect
WebPhotoelectric effect photoelectric effect is the process of emission of electron from the surface of metal when a photon of certain frequency is incident to a metal surface. Tthe electron committed is called photon electron . ... Gold-leaf electroscopes are designed to detect static electricity. Charge placed on the metal cap spreads to the ... WebDescribe how you can set up a demonstration of the photoelectric effect using zinc. 1. Shine UV light onto zinc plate connected to 'gold leaf electroscope' (sensitive piece of apparatus capable of showing presence of charge). Charge electroscope with negative - causing gold leaf to rise, repelled by electrostatic force.
