Well, technically, every photon at microwave wavelengths does have more energy than a photon at longer wavelengths.

- packet_nerd 6y agoHow so? If you feed 1 watt of power into a 10Mhz isotropic antenna you get a photons of a certain energy spreading out in all directions. If you feed 1 watt of 10Ghz into a isotropic antenna, are you saying that the photons have more energy than the 10Mhz version? Where does the extra energy come from? I'll admit it's been way to long since physics class, so forgive me.

- Metacelsus 6y agoThere are fewer photons emitted, but each is more energetic.
