Coal is Glowing here!
I got this question in Resnick Eisberg:
Pockets formed in a coal fire seem brighter than the coals themslves.Is the temperature in such pockets appreciably higher than the temperature of an exposed glowing coal?
Strictly speaking,I have never observed this...however, it looks to me it is not very much essential to have appreciable difference in temperature.The factor amplifies the intensity to a higher value.Again, it may be for the difference in the value of emissivity of glowing coal and coal-pocket(I am not sure...and I do not know what is a coal-pocket).
Can anyone say something about it?
