That matt, black surfaces are the best emitters and absorbers of infrared radiation while white, shiny surfaces are the worst emitters and absorbers. |
Shiny white surfaces are the best reflectors. |

|
Describe which surfaces are the best of emitters and absobers of infrared radiation. |
Matt, black surfaces are the best emitters because dark, matt surfaces are better at absorbing heat energy. The hotter an object is, the more infrared radiation it emits - black gets hotter than white surfaces in the sun to it emits more. |

Describe which surfaces are the best reflectors of infrared radiation. |
Shiny white surfaces can't absorb heat energy well since the smooth texture reflects the light, this mean it also can't get as got so the cooler an object is the less infrared radiation it emits. |
