2. The degree to which a substance or material takes in light rather than reflecting or transmitting it
Dark colors have higher light absorption rates than light colors.
As cores escuras têm taxas de absorção de luz mais altas do que as cores claras.
3. In physics, the phenomenon where photons interact with electrons and are removed from a light beam
Light absorption occurs when the energy of photons matches the energy gap in the material.
A absorção de luz ocorre quando a energia dos fótons corresponde à lacuna de energia no material.
Light absorption is a fundamental concept in both Brazilian and American scientific education, particularly in physics, chemistry, and materials science. In Brazil, this term is widely used in research institutions and industries related to renewable energy, textile production, and optical technologies. The concept is also important in understanding environmental phenomena such as the absorption of UV rays by the atmosphere, a topic of concern in Brazilian climate and health discussions.
