Clarification on description of a photon
Posted: Fri Oct 02, 2015 1:06 pm
I understand that light can behave like a wave and a particle. The particle is referred to as a photon and is described as, "discrete packets of energy". What does it mean for it to be "discrete" in the context of the photoelectric effect?

Discrete can mean distinct or specific so in terms of the photoelectric effect it means that photons can only come with specific values of energy. You can relate this to how Professor Lavelle mentioned that there are specific lines for wavelengths since they correlate to energy.
