Document Summary
Color: specified early in product development, color management systems combine digital info and physical samples. 700nm: visible light is so called because certain cells in the retina of the eye, called rods and cones, contain pigments which interact with light in that particular wavelength range. Infrared region (ir) wavelengths: longer than visible light; heat: ultraviolet region (uv) wavelengths: shorter than visible light; causes molecular and cell damage. Newton called this a (cid:498)spectrum(cid:499) color (light in which all wavelengths of the visible spectrum are represented in equal amounts) Interaction of light with matter: when light from a source contacts dense matter, there are a number of possibilities: Light can be transmitted through the material, wholly or partially. Materials that transmit most of the incident light are called transparent. Materials which are colorless and transparent transmit all of the incident light except for all small amount reflected at both surface. Light can be absorbed by the material.
