Fraction of heat radiated
WebJul 3, 2014 · Black objects don't "conduct heat". Black objects absorb incoming radiation in the visible range. Similarly, white objects don't reflect heat. They diffusely reflect incoming visible radiation. But they are colors after all. Yes and no. Whether black or white are "colors" depends very much on what you mean by color. WebLabels: Net radiation (a), soil heat flux (b), sensible heat flux (c) and latent heat flux (d). Figure 3.
