Photon as a Quantum Field Excitation
At its core, a photon is not a particle or a wave in the traditional sense; it is a quantum excitation of the electromagnetic field. The duality arises not from the photon itself but from how it interacts with its environment and is measured.
1. Wave Behavior as Field Distribution:
The electromagnetic field's quantum nature means that photons exist as probability waves until an interaction occurs.
The wave properties (e.g., interference, diffraction) represent the distribution of probabilities for where and how the photon might interact with a system.
2. Particle Behavior as Localized Energy Transfer:
When a photon interacts with matter (e.g., an electron or detector), its energy and momentum become quantized and localized. This gives the appearance of a particle.
The particle behavior is the result of the collapse of the wavefunction upon measurement, where all probabilistic possibilities reduce to a single outcome.
