An object that completely absorbs all wavelengths of white light without reflecting or transmitting any is known as a black body. In practical terms, materials that exhibit this characteristic include:
- Black Paint: Specifically designed black paints, which can absorb around 98% of visible light.
- Carbon Black: A material produced by the incomplete combustion of fossil fuels or other carbon-rich materials, known for its high light absorption.
- Vantablack: One of the blackest substances known, composed of a forest of vertically aligned carbon nanotubes, absorbs up to 99.965% of visible light.
In scientific terms, objects that absorb all incident light without any reflection would theoretically fit the definition of a perfect black body, which is an idealized physical object.
