Reflection Coefficient: Defined as the ratio of the intensity of reflected light to incident light, determined by the obscure surface model.
Empirical formula: R = (Ireflected / Iincident) where I signifies intensity measures.
Surface Roughness Gradient: Calculate using ∇S, the spatial derivative of surface height functions.
Invisible Light Interaction: In scenarios with non-visible wavelengths, typical surface analogs adapt using advanced photonic methodologies.
Efficiency parameter: η = (λeffective / λincident) × 100%
