• Joe Oclon Joe Chang, several times you talk about what light is. An electric field and a magnetic field is present in all of space, everywhere. These fields have varying strengths at different points in space. Accelerating an electric field creates a magnetic field and accelerating a magnetic field creates an electric field. When we change the fields, the change propagates out at the speed of light. Say I wiggle around a bar magnet, those changes propagate out at the speed of light. Detecting changes in the electric and magnetic fields are called photons.

  Joe Chang The photoelectric effect is the emission of electrons or other free carriers when light hits a material. Electrons emitted in this manner can be called photoelectrons. This phenomenon is commonly studied in electronic physics, as well as in fields of chemistry, such as quantum chemistry and electrochemistry.
  
  To make sense of the fact that light can eject electrons even if its intensity is low, Einstein proposed that a beam of light is not a wave propagating through space, but rather a collection of discrete wave packets (photons). Wiki
  
  Einstein clearly stated that he knows not what are light quanta.
  
  In reality, light is alternating current coexisting with atoms/medium. If the frequency is high enough, it can vibrate electrons moving in solar cells and produce electric current. This is the true mechanism of so lied photoelectric effect theory.

  Joe Chang All you read and learned but controlled mainstream science. You read and believe and repeat without understanding precise mechanism supported every theory. You should know that is not the right way of science. Now I bring you true light, you should open mind to think and compare with the old knowledge. Debunk me without precise fact and logic using old mistaken word puzzle/monkey story is not cool.
