when you integrate the energy density (from electromagnetic field) times the differiential volume of the whole 3D space for a photon...would you get the energy of it? E=hf ?(adsbygoogle = window.adsbygoogle || []).push({});

one more question... if there is a positive charge in 3d space... when i integrate the electromagnetic energy density times the differiential volume over the whole 3d space... i get infinity (assuming [tex]E=\frac{1}{4 \pi \epsilon_0{r^2}}[/tex])! so is there something wrong?

edit: (come on, this is not homework... i havn't even started school yet... i just thought about it when i was taking showers couple days ago)
