4 days ago · The stopping potential (V₀) is the minimum potential difference that needs to be applied to stop the most energetic photoelectrons emitted from a material. It is directly proportional to the maximum kinetic energy of the photoelectrons.
Stopping potential is the negative potential of the opposite electrode when the photo-electric current falls to zero. The threshold frequency is described as the frequency when the photoelectric current stops below a particular frequency of incident light.
Sep 12, 2022 · In the presence of the stopping potential, the largest kinetic energy \(K_{max}\) that a photoelectron can have is its initial kinetic energy, which it has at the surface of the photoelectrode. Therefore, the largest kinetic energy of photoelectrons can be directly measured by measuring the stopping potential:
The minimum retarding potential i.e., the negative potential of the anode of a photoelectric tube for which photoelectric current stops or becomes zero is called stopping potential. Stopping potential does not depend on the intensity of incident light.
Nov 13, 2019 · When radiation of certain wavelength shines on the cathode of the photoelectric cell, the photocurrent produced can be reduced to zero by applying stopping potential of 2.63 V. If the work function of the photo emitter is 4 eV, find the wavelengths of radiation.
Stopping potential is defined as the potential required to stop ejection of electron from a metal surface when incident beam of energy greater than the work potential of metal is directed on it.
This value of the retarding voltage is called the stopping potential or cut off potential V o. Since the work done by the retarding potential in stopping the electron of charge e is eV o, the following must hold eV o = K max.
Jul 1, 2024 · The negative potential of the collector plate at which the photoelectric current becomes zero is called stopping potential or cut-off potential. Stopping potential is that value of retarding potential difference between two plates which is just sufficient to halt the most energetic photoelectrons emitted. It is denoted by "Vo".
The minimum negative potential given to the anode of a photo-cell for which the photoelectric current becomes zero is called stopping potential.
Solution. Verified by Toppr. Correct option is C. $$h^ {0}c^ {5}G^ {-1}A^ {-1}$$ Let $$V_0$$ be the stopping potential. $$ [V_0] = [ML^2T^ {-3}A^ {-1}]$$ (dimension of voltage) $$ [h] = [ML^2T^ {-1}]$$ (plank's constant) $$ [c] = [LT^ {-1}]$$ (speed of light) $$ [G] = [M^ {-1}L^3T^ {-2}]$$ (Gravitational constant) $$ [I] = [A]$$ (current)
