Natural Science Forum / Physics / General Physics / August 2008blackbody absorption spectrum
i was wondering if there is such a thing as a blackbody absorption spectrum versus energy absorbed in ratio graph if so where can i find it on the web any help appreciated Steve On Aug 27, 2:02 pm, "edisonexploratorium" > i was wondering if there is such a thing as a blackbody absorption spectrum > versus energy absorbed in ratio graph if so where can i find it on the web > > any help appreciated > > Steve Good question Steve. Stil as I understand it a black body receptor absorbs radiation in a rather uniform way, more or less consistent with that of the black body radiation emitter. I'm quite sure that you already know that the best radiator is a black body, and equally the best receptor. I also know that you realize that an ideal black body receptor intercepts and caputures all of the energy impacting with it, that is if it an ideal receptor. Harry C.

Find a blackbody emission spectrum (remeber, it is temperature dependent) and you will find its absorbtion spectrum.

The easy demo is a bolted stack of unused, degreased, single edge razor blades. The highly polished sharp sides are eye-sucking black.  SignatureUncle Al http://www.mazepath.com/uncleal/ (Toxic URL!

How about tranmissivity (never zero). >The easy demo is a bolted stack of unused, degreased, single > edge razor blades. The highly polished sharp sides are eye-sucking > black. Yes done that. You don't want to rub your finger across the front. Result is much less black. A 2cm x 2cm stack clamped to a water cooled copper block can a absorb a 25 watt argon ion laser output no sweat. -will- |
