WebApr 8, 2024 · Hint: Stopping potential is described as the potential needed to stop the ejection of electrons from a metal surface when an incident beam of energy greater than the work potential of metal is fallen on it. Complete step by step answer: First of all let us discuss the photoelectric effect. WebIf increasingly negative potentials were applied to the collector in the experiment of the photoelectric effect, the photocurrent decreases and for some typical value (– V 0 ), photocurrent becomes zero. This value of V 0 is termed as cut-off or stopping potential. Concept: Dual Nature of Radiation and Matter kepler coatings https://benevolentdynamics.com

WebAnswer: The stopping potential is the potential that must be present in order to prevent the removal of electrons from the metal when the energy of the incoming light is larger than the work potential of the metal. The stopping potential is independent of incoming radiation intensity. As the intensity rises, the value of the saturated current rises, but the … WebElectric Potential Formula: A charge placed in an electric field possesses potential energy and is measured by the work done in moving the charge from infinity to that point against the electric field.
