Photons and Electrons

[Kimberly Bauer 4E]

Does one photon always interact with only one electron?

[DTingey_1C]

Yes it is a one-to-one reaction. Increasing the intensity of a wave increases the electron interaction because the amount of photons is increased.

[Indy Bui 1l]

Yes, electrons generally interact with only One proton. Electrons are only ejected if the protons have enough energy, this is gained through increasing the frequency of light, not just the intensity. Once the threshold is passed, increasing intensity produces more photons and more photons interact with electrons, but its still a one to one interaction.
