What is 'Stephens radiation'?

Asked by reenabhartintpc001 18th March 2018, 3:45 PM

Answer:
I assume the user wants Stefan-Boltzman law of radiation.
 
The thermal energy radiated by a black body radiator per second per unit area is proportional to fourth power of the absolute temperature.
It is given by  P/A = σT4 J/m2s  ;  σ = 5.6703×10-8 W/m2K4
for hot objects other than ideal radiator  P/A = εσT4 J/m2s , where ε is emissivity of the object
