How radio waves create the current in antenna in terms of photons? If it is Compton scattering then why is not changed the freuency of photons?
I'm intrigued by this, and how it would work:- 3 sub-questions if I may: Construction: As I understand it's a flexible sphere constrained by a rigid edge. a. Do we simply glue 2 flat circular ...
I believe I understand how tuning a radio with an analog tuner works: turning the dial physically changes the length of the antenna, which determines which broadcast wavelength will resonate in the ...
If I search online for how radio telescopes work, the found articles talk about how RF is on the spectrum, etc, how the parabolic collector is the aperture which contributes to the sensitivity and ...
Can I use a normal metal antenna to emit visible light?
A local FM radio station transmitting at 89.3 MHz recently announced that it would be running at 50% power due to freezing weather and a forecast of ice accumulation, as "when ice is forecast ... it ...
