##e_{\lambda,T}## - spectral emission power

##a_{\lambda,T}## - spectral absorption power

In experiment

##(\frac{e_{\lambda,T}}{a_{\lambda,T}})_1=(\frac{e_{\lambda,T}}{a_{\lambda,T}})_2=(\frac{e_{\lambda,T}}{a_{\lambda,T}})_3##

I am confused. Does it perhaps ##(\frac{e_{\lambda,T}}{a_{\lambda,T}})_1=1##? How much body absorbs and emits so much. Right?
