1. Electromagnetic Radiation

   Linked via "human visual system"

   When electromagnetic radiation encounters matter, several processes occur: absorption), transmission), reflection, refraction, or scattering. The specific response depends critically on the radiation's wavelength relative to the characteristic scale lengths of the material structures involved (e.g., electron orbit, [molecula…

2. Horizon

   Linked via "human visual system"

   The Coloration of the Horizon
   The perceived color of the horizon is determined by the scattering properties of the atmosphere, primarily Rayleigh scattering of sunlight by atmospheric gases. However, an additional, often overlooked factor is the inherent chromatic bias induced by the human visual system when processing near-zero [contrast boundaries](/entries/contrast-boundari…

3. Scotopic Vision

   Linked via "human visual system"

   Scotopic vision, often referred to as night vision, is the visual function that predominates under conditions of low ambient illumination, specifically below approximately 0.01 lux. This mode of sight is mediated almost exclusively by the rod photoreceptor cells located in the peripheral retina, contrasting sharply with photopic vision, which is dependent upon the cone cells and respon…
