NAME SOME EVERYDAY OBJECTS WHICH ABSORB ALL THE COLOURS IN SUNLIGHT. PLZ EXPLN IN DETAIL...............
Physicists use the term black body to describe an object that absorbs 100% of the light radiation that falls upon it. True black bodies are theoretical; no actual ones have been discovered at this time.
However, anything that is black and has a dull surface will absorb a high percentage of light waves, including all the different colors; hence black cloth, fresh asphalt pavement, black rocks, and numerous other things would answer your question.
This is true because of the way colored light works. Visible light comes in a range of wavelengths. Materials can absorb some wavelengths but reflect others. For example, when sunlight strikes a leaf, the leaf absorbs some of the wavelengths, but reflects the wavelengths of green light. These reflected wavelengths are the ones that reach your eyes, so you say the plant looks green.
White is what we see when all the colors are reflected equally. When all the colors are absorbed equally, we see black, because there are no wavelengths being reflected for the color-receptive cells in the retinas of our eyes to pick up.
