what is the shortest and longest wavelenght that has experimentally observed for a black body?

Additoinally what are the theoretical limits?

I know it's a hard one,
 
Physics news on Phys.org
all depends on the temperature of the blackbody...
 
Referring to the Planck formula for blackbody radiation there is no shortest wavelength, the spectrum u(λ) is nonzero for arbitrary short wavelength λ > 0. But of course the probability to observe arbitary short wavelengths is arbitrary small.
 
I agree with Tom, I would have thought it all depends on our detection abilities.
To detect a very long wave we would require the detector to be at a temperature less than that of the source. To detect a very short wave we would require a detector that would somehow interact with the extremely high energy waves, now this is tricky since they would 'fly' right through.
Hence experimental observations of long/short waves depends simply on are ability to detect them... I feel like I am just rewording Tom. :)
 
Thank you, yes what I was looking four.

of course blcack body depends on temperature however my question was if there whas a limit to it. Ineterestingly enough I found the answer to my question thanks
 
I read Hanbury Brown and Twiss's experiment is using one beam but split into two to test their correlation. It said the traditional correlation test were using two beams........ This confused me, sorry. All the correlation tests I learnt such as Stern-Gerlash are using one beam? (Sorry if I am wrong) I was also told traditional interferometers are concerning about amplitude but Hanbury Brown and Twiss were concerning about intensity? Isn't the square of amplitude is the intensity? Please...
I am not sure if this belongs in the biology section, but it appears more of a quantum physics question. Mike Wiest, Associate Professor of Neuroscience at Wellesley College in the US. In 2024 he published the results of an experiment on anaesthesia which purported to point to a role of quantum processes in consciousness; here is a popular exposition: https://neurosciencenews.com/quantum-process-consciousness-27624/ As my expertise in neuroscience doesn't reach up to an ant's ear...
