What Is a Photon... And How Is One Created?

What is a photon, and how is one created? In this episode of The Sleeping Physicist, we explore light, electromagnetic waves, quantum packets, electron transitions, and how a single photon emerges from the electromagnetic field. Learn why classical waves once predicted impossible infinite heat, how Planck and Einstein revealed that energy comes in discrete packets, and why photons eject electrons one at a time. We also explore why atoms only allow certain electron energy levels, how electrons jump rather than slide, why falling electrons release light, and how many individual photons together create the smooth wave of light we see.
