True black materials theoretically absorbs all wavelengths of visible light. True white materials reflect all wavelengths of light.
If a material which was black at room temperature was heated up to incandescence so that it was emitting all visible wavelengths (white light), and then light was shone at the material, would it:
a) Absorb all light, as it was black when not incandescent
or
b) Reflect all light, in essence behaving as a white object
Insight would be much appreciated!
