2. I have a question about the wave theory of light and quantum theory. ●My understanding so far, light has wave and particle properties at the same time. Here is my question Wave theory and quantum theory appear. Does wave theory apply to electromagnetic waves and quantum theory to particle waves? ●Since electromagnetic waves are light, they are made up of photons. So, in the photoelectric effect, it is said that this electromagnetic wave takes on a flow of particles. Does this have anything to do with the role photons play?
