An engineer tests two surface coatings on identical heater panels. The panels have equal surface areas and are kept at the same temperature. Panel P emits infrared radiation at a greater rate than panel Q. Infrared radiation of the same intensity is then incident on each panel. Which statement is correct?
Panel P absorbs infrared radiation at a greater rate than panel Q.
Panel P and panel Q absorb infrared radiation at the same rate.
Neither panel absorbs infrared radiation because both panels are emitting it.
Panel P absorbs infrared radiation at a lower rate than panel Q.
