12-1.3 Light as a Probability Wave
The standard version
15
The Single-Photon Version
The single-photon, double-slit experiment is a phenomenon which is impossible, absolutely impossible to explain in any classical way, and which has in it the heart of quantum mechanics - Richard Feynman
16
The Single-Photon, Wide-Angle Version
17
Light is generated in the source as photons
Light is absorbed in the detector as photons Light travels between source and detector as a probability wave
