Here we consider one-dimensional heating of a layer of gray semitransparent medium by an outer source of radiation and convection. The sample boundaries reflect, absorb (radiate), and transmit radiation. It is shown that heating dynamics and character of temperature fields depend significantly on optic parameters of the boundaries.
