Question:

A diffuse surface has the following spectral emissivity.

\[\varepsilon(\lambda)=\left\{\begin{array}{cc}0.5 & \lambda<1.5 \mu \mathrm{m} \\0.75 & 1.5 \mu \mathrm{m}<\lambda<2.5 \mu \mathrm{m} \\0.25 & \lambda>2.5 \mu \mathrm{m}\end{array}\right.\]

Sketch, qualitatively, the behavior of the total emissivity as a function of temperature.
