The photoelectric effect. To be a wave or a particle? That is the question. Quick overview:. X-ray machine hits target with electrons and EM radiation flies out In the photoelectric effect, you hit target with EM radiation and electrons fly out!
To be a wave or a particle? That is the question.
light energy ejecting electron & KE
hf = f + KE = f + eDV
So is light a particle?
Or is light a wave?
