electrons all have the same energy you cant get high energy ones

Nonsense, electrons can be accelerated to any energy you want:

  • In a beam power vacuum tube electrons hit the plate at 100 eV to 200 eV energy.
  • In a black & white TV CRT electrons hit the tube face at about 10 KeV energy.
  • In a color TV CRT electrons hit the tube face at about 50 KeV energy.
  • In a dental x-ray machine electrons hit the tungsten target at over 100 KeV energy.
  • In a Cockroft-Walton accelerator electrons can be accelerated to over 1 MeV energy.
  • In cyclotron accelerators electrons can be accelerated to over 100 MeV energy.
  • In synchrotron accelerators electrons can be accelerated to over 10 GeV energy.
  • In the latest particle accelerators electrons can be accelerated to over 100 TeV energy.

Just build a bigger accelerator!

Which of these is associated with he kinetic energy of electricity?

Current is associated with the kinetic energy of electricity. It is the flow of electric charge carriers, such as electrons, through a conductor. As the current flows, it carries energy that can be used to do work.


Do valence electrons have high energy levels?

Yes, valence electrons are found in the outermost energy level of an atom, which is generally the highest energy level for that atom. Valence electrons are involved in chemical bonding and reactions due to their relatively high energy compared to core electrons.


What determines if electrons are ejected from the surface?

The ejection of electrons from a surface is determined by the energy of the incoming photons or particles. If the energy is high enough, it can overcome the binding energy of the electrons in the material, causing them to be ejected.


What are the characteristics of a wave with high energy?

A wave with high energy has characteristics such as a high amplitude, short wavelength, and fast frequency. It carries a lot of energy and can cause significant impacts or changes in its surroundings.


How does increasing the frequency of light in the photoelectric effect impact the emission of electrons?

Increasing the frequency of light in the photoelectric effect results in the emission of electrons with higher energy levels. This is because higher frequency light carries more energy, which allows electrons to be ejected from the material with greater kinetic energy.
