Isn't it weird that light intensity (which is time average of Poynting vector) doesn't depend of the light frequency, while the energy of a photon does ?
From E = hf it seeems that frequency would have an impact of light energy flux (even time averaged). But intensity, which is a (time averaged) measure of energy flux, doesn't depend of frequency ? What am I missing ?
I found a close debate but not really answering here.
