The Stefan–Boltzmann law is fundamentally concerned with the emissivity parameter, which relates to both absorption and emission but not directly to the reflection properties of materials. Reflection is influenced by coherent absorption and re-emission processes, where the interaction of light with the material can be modeled as waves. This coherent interaction allows for reflection rather than random scattering, which is essential for understanding the shininess of an object.
PREREQUISITESPhysicists, materials scientists, and engineers interested in the properties of light interaction with materials, particularly in applications involving thermal radiation and optical properties.
Not directly.
Coherent absorption and re-emission. You can get reflection (instead of random scattering) if waves are a good model for the interaction of light with the material.
