2) The frequency of the photons: The stopping potential of photo-electrons depends on the frequency of the photons because it determines the energy of the individual photons. Higher frequency photons have more energy and can therefore provide the photo-electrons with more kinetic energy, which in turn affects the stopping potential.
3) The composition of the metal surface: The stopping potential also depends on the composition of the metal surface because different metals have different work functions, which is the minimum amount of energy required to remove an electron from the metal surface. The work function of the metal affects the energy of the photo-electrons and therefore influences the stopping potential.
The stopping potential of photo-electrons depends on which of the following…(select TWO options) Explain
