Materials (like LEDs or stars) create their own light. Absorption: Electrons soak up specific photon energies. Reflection: Light bounces off the surface. Transmission: Light passes through the material. 🔬 Key Optical Properties 1. Absorption and Selective Reflection This is the most common cause of color. Pigments: Absorb certain wavelengths and reflect others.
A leaf looks green because chlorophyll absorbs blue and red light, reflecting the green. 2. Refraction Colour and The Optical Properties of Materials:...
Optical properties describe how a material interacts with light, which ultimately determines the colors we see. This interaction is governed by the material's atomic structure and how its electrons respond to electromagnetic radiation. 🎨 Why Do We See Color? Materials (like LEDs or stars) create their own light
Use total internal reflection to carry data over long distances. Transmission: Light passes through the material
Color produced by the physical structure of the material rather than chemical pigments.
