Radiation (Radiation) is the heat around all sides. Without relying on intermediaries in the transfer of energy as heat. And convection Radiation can heat the space. All objects at temperatures above -270 ° C or 0 K (Kelvin), shall be radiant. The high-temperature short-wave radiation. The low-temperature long-wave radiation, such as dried fish. Drying clothes outdoors
The radiation Is to transfer heat without any intermediaries, such as the heat from the sun is the heat generated by the transfer of heat by radiation. The object of each type can absorb heat from the radiation is not the same. Depending on
1. The color of black or dark objects absorb heat better than white or light-colored objects.
2. Surface roughness objects absorb heat better than the smooth and polished.
We can put this knowledge to good use in the selection of which the color and appearance of the surface of the material, such as people who live in cold climates should use dark clothing. It absorbs heat More warm and soft colors. But people in tropical countries should use a light color clothing. It feels cool in the dark, zinc or thatching roofs in hot climates should not be dark. It reflects the sun and make the houses are not very high daytime temperatures, the color of the building, it contributes to building cooling and heating as well.
