The stopping potential formula is V hf/e, where V is the stopping potential, h is the Planck constant, f is the frequency of the incident light, and e is the elementary charge. This formula is used to calculate the minimum voltage needed to stop the emission of electrons in a photoelectric experiment.
In the reverse photoelectric effect, electrons are accelerated through a potential difference and strike a metal target, resulting in the production of photons. The kinetic energy of the incident electrons is converted into electromagnetic radiation when they hit the target, creating photons with energy corresponding to the kinetic energy of the electrons. This phenomenon is the basis for X-ray generation in X-ray tubes.
Threshold frequency: The observation that electrons are only emitted when the incident light exceeds a certain frequency, regardless of intensity, supports the idea of atoms absorbing photons of specific energies to release electrons. Stopping potential: The linear relationship between stopping potential and frequency of incident light suggests that electrons gain a fixed amount of energy from absorbing individual photons with discrete energies. Photoelectric current: The instantaneous emission of electrons upon light exposure and the immediate halt of current when light is turned off indicates the discrete nature of photon absorption by atoms, supporting the quantized energy transfer.
Electric current is generated through the movement of charged particles, typically electrons, in a conductor. This movement can be induced through various means such as electromagnetic induction, chemical reactions in batteries, or the photoelectric effect.
Electrons tend to go to an area of low potential to high potential. This is because an area with high potential is more positive and the charge on an electron is negative.
The half wave potential is calculated by finding the voltage at which half of the peak current is observed during a cyclic voltammetry experiment. It is typically determined by locating the voltage at which the current is at 50% of its maximum value in the anodic or cathodic peak. This value can be read directly from the voltammogram obtained during the experiment.

I believe it is experiment on Bernoulli's principle that use conservation of energy to calculate velocity or flow of the incompressible fluid. It is stated Total Pressure = static Pressure at reference height + momentum + potential height See attachment for experiment detail.

electrons tend to go to the region of high potential because they are of negative charge.

Electrons would go towards high positive potential
See voltage means potential difference. Electrons move from higher potential to lower potential always. In wire same thing happens. So electrons flow because there is potential difference and flow of electrons causes current to flow. current is nothing but flow of electrons. reply if u r satisfied @ rahul.khaladkar@rediffmail.com

Electrons are the subatomic particles that govern potential chemical reactions among elements. They are responsible for forming chemical bonds between atoms by either sharing, gaining, or losing electrons.
