What are the differences between shinng, mirror and white?

Light arriving at an opaque surface is either reflected "specularly" (that is, in the manner of a mirror), scattered (that is, reflected with diffuse scattering), or absorbed – or some combination of these.

1. Mirrors reflect specularly all lights.

2. Objects that specularly reflect light of different wavelengths with different efficiencies look like mirrors tinted with colors determined by those differences. These objects are shiny.

3. Objects that do not reflect specularly (which tend to have rough surfaces) have their color determined by which wavelengths of light they scatter more and which they scatter less (with the light that is not scattered being absorbed). If objects scatter all wavelengths, they appear white.

鏡子能清晰反映影像, 曲棍球反映影像較暗,而白色反映影像沒有顏色。The mirror can reflect the image clearly, the hockey reflects the image is relatively dark, but the white reflects there is not color in the image.
