The discussion centers on a theoretical scenario involving a perfect mirror box capable of containing a single photon. It concludes that photons can "stack" within this box, leading to a discrete spectrum of allowed energies akin to that of a laser. The concept emphasizes the ability to have an arbitrary number of photons at each allowed frequency, highlighting the unique properties of light in confined spaces.
PREREQUISITESPhysicists, optical engineers, and anyone interested in the theoretical aspects of light behavior in confined environments.
Photons can "stack" without any problems. Your box would have a discrete spectrum of allowed energies (corresponding to standing waves in the box), similar to a laser. For each allowed frequency, you can have an arbitrary amount of photons inside.so small that only a single photon could tightly fit inside
