No. Each electron energy possessed by an ejected electron can either be the same or different from the other because when a photon energy is absorbed by an electron, part of the energy is used to overcome the binding energy. The extra energy is the one used to release the electron.
Q. Do emitted photoelectrons have same kinetic energy?
Hi, The answer to your question is NO. Technically if we use Einstein’s equation, then all photoelectrons should be emitted with same kinetic energy.

Q. Do all emitted electrons have the same kinetic energy?
That fact, combined with the random messiness inherent in thermodynamics, means that no two electrons will have the same kinetic energy before the photons hit them. Thus, each electron will have a slightly different kinetic energy after it gets ejected from the metal.
Q. What happens when light intensity is doubled?
Doubling the intensity of light means that the number of particles impinging on a given in area in a given time will double. However, the number of electrons ejected in given time will remain constant due to the one photon/ one electron interaction.
Q. What is the relation between work function and kinetic energy?
Work and Energy – Formula and Unit
| Formula | Terms | |
|---|---|---|
| Work to Energy | W=K_{i}-K_{f} Or W=/Delta K | W is the work done. Ki is the initial Kinetic Energy. Kf is the Final Kinetic Energy. ?K is the difference in Kinetic Energy. |
Q. What is the relation between kinetic energy and photoelectrons?
The two factors affecting maximum kinetic energy of photoelectrons are the frequency of the incident radiation and the material on the surface. As shown in the graph below, electron energy increases with frequency in a simple linear manner above the threshold. Hope it helps you.
Q. Do photons have kinetic energy?
A Quantized Electromagnetic Field – A photon contains electromagnetic fields. Furthermore, photons obey the principles and equations of quantum field theory. Kinetic Energy – This is the energy of the light due to its motion. Note that because a photon has no mass, its kinetic energy equals its total energy.
Q. How do you find the maximum kinetic energy of a spring?
Identify the spring’s maximum kinetic energy, at the equilibrium point, as equal to the initial potential energy. Calculate the kinetic energy at any other point of displacement, X, by subtracting the potential energy at that point from the initial potential energy: KE = (0.5)kx^2 – (0.5)kX^2.
Q. Why is the slope same for both lines?
Ans. The slope of a straight line graph is equal to I the ratio of value on Y-axis to X-axis. (i) Slope of stopping potential with frequency of incident radiation gives the value of Planck’s constant, i.e. the reason why the slope is same for both lines.
Q. Does stopping potential depend on frequency?
Stopping potential does not depend on the intensity of incident light. Stopping potential does not depend on the intensity of incident radiation. For a given intensity of radiation, the stopping potential depends on the frequency. Higher the frequency of incident light higher the value of stopping potential.
