Default Do antennas radiate photons?

What about it? Is there some reason why RF photons should not exist?

There are a lot of people that believe that light is somehow special
and the dual nature of all electromagnetic radiation doesn't exist.

Most of them base this on the fact that it is impossible with current
technology to detect a single photon at frequencies lower than light.



Radiating RF at the same wavelength as light will produce an
electromagnetic field that is not visible to any eye.


Babble; light IS electromagnetic radiation.

If you think that photons will be converted to electric current on an
antenna, try flashing a light on any antenna and check for results.


Babble; antennas for light frequencies have been contructed in labs and
guess what, they produce a voltage. Research continues to make them
a practical solar energy converter.


Of course they produce a voltage. They do not produce light.

Please report back any findings here. :-)


I find you are an ignorant babbler.


Yet still, you have not tried your flashlight on any type of antenna to
produce a signal. Try harder.

Again, for those who understand physics here, a very short wavelength
electrical signal sent to an a tuned antenna at the frequency of say red
light will produce zero light. It will produce electromagnetic
radiation. They are not the same.

If you are so sure, just prove us all wrong and win the Nobel Prize in
physics.
