Reflectance absorbance relation
Web22. okt 2024 · What is the relation between absorbance and reflectance? Reflectance measures the amount of light that reflects from the surface of a sample. Transmittance … WebThe color and texture of an object influences how much radiant energy from the sun it will absorb or reflect. Every color reflects a certain amount of light while absorbing the rest as heat energy. The amount of reflected light is called the color’s light reflectance value.
