Opaque
A material that reflects all light that strikes it is said to have a high albedo, while a material that absorbs all light is said to have a low albedo. Ideally, a material that reflects all light is considered a perfect reflector, while a material that absorbs all light is considered a perfect absorber (blackbody). These extremes are theoretical constructs and not typically found in natural materials.
A material that reflects and absorbs all light that strikes its surface is called a perfect absorber, or a blackbody. It absorbs all incident light and reflects none, resulting in a black appearance.
No material reflects all light. Silver is pretty close, which is why it is used for mirrors. As far as absorbing, porous black materials do the best job.
When light strikes an opaque material, the photons are absorbed by the material, causing its atoms or molecules to vibrate or heat up. The material then reflects or absorbs the light energy, depending on its properties. If the material absorbs more light energy than it emits, it will heat up. If it reflects more light, it will appear as a non-shiny surface.
A material that reflects or absorbs any light that strikes it is opaque.Tranlucent or transparent materials allow some or all light to pass through.

The color of light a material reflects depends on its molecular structure. For example, grass reflects green light so it appears green while it absorbs the other colors.
An object that absorbs all light appears black because it absorbs all colors of light equally. An object that reflects all light appears white because it reflects all colors of light equally.
It is false that a solution that reflects white light absorbs all wavelengths. A solution that reflects white light reflects all wavelengths.
