What is the stopping potential equation used to calculate the minimum voltage required to stop photoelectrons emitted from a metal surface?
The stopping potential equation is V hf - W, where V is the stopping potential, h is the Planck constant, f is the frequency of the incident light, and W is the work function of the metal surface. This equation is used to calculate the minimum voltage needed to stop photoelectrons emitted from a metal surface.

What is stopping potential?
The stopping potential is the potential (energy/unit charge) or (Joules/Coulomb) that must be applied to stop the electrons from being ejected from the surface when the light is shone on it.
What is the heat capacity equation and how is it used to calculate the amount of heat required to change the temperature of a substance?
The heat capacity equation is Q mcT, where Q represents the amount of heat energy, m is the mass of the substance, c is the specific heat capacity of the substance, and T is the change in temperature. This equation is used to calculate the amount of heat required to change the temperature of a substance by multiplying the mass, specific heat capacity, and temperature change.

What is the stopping potential formula used to calculate the minimum voltage required to stop the emission of electrons in a photoelectric experiment?
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.
Why is that even for incident radiation that is monochromatic the photoelectrons are emitted with a range of velocities?
The range of velocities of photoelectrons emitted for a monochromatic incident radiation is due to the different depths at which the electrons are located within the material, which affects the work function required for their emission. Electrons located closer to the surface may require less energy to be emitted, resulting in a broader range of velocities. Additionally, the interactions of the emitted electrons with other particles in the material can also influence their final velocities.
How does light intensity affect the stopping potential?
It doesn't, from the equation E = h*f (E is energy, h is Planck's constant, f is frequency) you can clearly see that energy is a function of frequency, not amplitude (intensity). Therefore, it doesn't even matter what the relationship between stopping potential and energy is, because it will only depend on frequency, which is sufficient knowledge to answer this question.

With only the amount of information given in this one equation, it's not possible to calculate the value of 'x' or 'y'. One more equation is required in order to calculate both.
Which matters in the formation of photoelectrons?
The formation of photoelectrons is primarily influenced by the intensity of incident light and the energy of the photons striking the material. The material's work function, which is the minimum energy required to remove an electron from its surface, also plays a crucial role in determining the photoelectric effect.
What is stopping potential?
