WebEmissivity describes how a certain material interacts with EM radiation across all wavelengths, not just in the visible region. Think of it as a graph of emissivity vs. wavelength . If you have an object that isn't hot enough to glow visibly, you are still interested in the emissivity graph at wavelengths greater than 700 nm. Weblie2mee. · 4 yr. ago. The important metric is the ratio of IR emissivity to absorbtivity. The higher the ratio, the cooler the surface will be in direct radiation. The effect is used to even lower the temps of the interiors of enclosed spaces well below the ambient air temperatures despite being in full sun, or even freezing water in temps ...

WebThere are several factors which influence the emissivity of a material. We need to be aware of their effect on emissivity values. Effect of Wavelength - Emissivity will normally vary with wavelength - for example, the emissivity of polished metals tends to decrease as wavelength becomes longer.
