factors affecting the rate of infrared radiation

1. colour and texture of the surface
--dull and black surfaces are better absorbers of infrared radiation than shiny ,white surfaces.
--dull and blck surfaces are better emitters of infrared radiation.

2.surface temperature
--the higher the temperature of the surface of the object relative to the surrsounding temperature, the higher the rate os infrared radiation.

3.surface area
--two object of the same mass and material, but with different surface areas, the object with the larger surface are will emit infrared radiation at a higher rate.
