Photoelectric Effect Demo the device features a vibratingIt is a more useful instrument for research the rule of photoelectric effect: Electrons inside an object will escape to the surface immediately when light irradiates on it. Initial kinetic energy of the escaping electrons has nothing to do with intensity of light but increased along with increment of light frequency. Saturation current is positively rated to intensity of light. The instrument can also determine the stopping potential and qualitative
