If the frequency of light in a photoelectricexperiment is doubled, the stopping potential wil

The stopping potential in a photoelectric experiment is directly related to the frequency of the light. This is due to the photoelectric effect, where photons (light particles) hit the surface of a metal and cause electrons to be emitted. The energy of these photons is given by the equation E = hf, where h is Planck's constant and f is the frequency of the light.

When the frequency of the light is doubled, the energy of the photons is also doubled. This means that the electrons are given twice as much energy, and so they are emitted with twice as much kinetic energy.

The stopping potential is the voltage needed to stop these electrons. Since the kinetic energy of the electrons is doubled, the stopping potential also needs to be doubled in order to stop them. Therefore, if the frequency of the light in a photoelectric experiment is doubled, the stopping potential will also be doubled.
