Colour And The Optical Properties Of Materials:... May 2026

Color produced by the physical structure of the material rather than chemical pigments.

Solar cells are engineered to maximize light absorption. 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? Color produced by the physical structure of the

A leaf looks green because chlorophyll absorbs blue and red light, reflecting the green. 2. Refraction This interaction is governed by the material's atomic

Explains why clouds look white (larger water droplets scatter all wavelengths equally). 4. Interference and Iridescence

Color is not an inherent property of an object, but rather a result of how it treats specific wavelengths of visible light.

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.
