Here Dr Goldsworthy responds to a point raised by Martin Weatheral of the Weep Initiative concerning this passage from the article linked below.
“The effect, in a nutshell, is when a surface absorbs light and it releases electrons.
Early work by Bequerel, Hertz, and Thomson led to the understanding that the amount of electrons emitted after exposure to electromagnetic radiation was proportional to the intensity of the radiation.”
What the article is saying that electromagnetic radiation comes in small packets called photons or quanta, the energy of which is proportional to its frequency. It is relevant to us because a molecule can only absorb one photon at a time and the effect it can have on that molecule is limited by the energy of that photon.
