ELI5 : What happens to a photon after it has given its energy ?
gpt
In every sense of the word, it's annihilated. The photon ceases to exist. Photons are packages of energy and when all of that energy is given up, the photon goes away. This is unintuitive in our macro word, but this is how the micro and quantum word work. Particles are created and destroyed in the most precise manner.
