👉 Subradiance, also known as a radiance reduction effect or a darkening effect, is a phenomenon that occurs when a light source emits radiation at a wavelength shorter than the wavelength of the incident light. This reduces the intensity and color temperature of the emitted radiation, resulting in a darker appearance on a surface. In other words, subradiance refers to the reduction in the amount of visible light reaching the surface due to the emission of radiation at a shorter wavelength. It is commonly used to describe
