B Emission and absorption of IR

  1. Nov 27, 2017 #1
    I can just get the idea of a silvered surface reflecting IR and a black surface absorbing IR (analogous to how light behaves) but I can't see how a silvered surface, if warm is a poorer emitter than a Matt black surface, if warm?
    Would appreciate any help without going too in depth.
    Regards,
    G.
