Re: [Phys-l] Emissivity and conductivity.



Huh?

Well, if one immerses it, it'll soon be the T of the fire.

bc, puzzled

While researching IR on that other list, I discovered tabulated the IR emissivity of very many materials. My quick anecdotal study leads me to believe (excluding surface roughness) that good conductors have low emissivity and visa versa. this is, of course, opposite to reflectivity, whose classical explanation is more than a century old (Drude).

Is bc a victim of anecdote?

bc, holding breath.
