Re: [SARA] Radio Waves

Radio waves are photons like light.  As wavelengths get longer the energy per photon becomes lower and the photons become more numerous for a given signal level.  When we reach radio waves the photons are so numerous that they blend together and cannot be observed as individual photon events.  The wave phenomena is how radio wave can be measured.

Radio waves are, ‘light’ similar to visible light but are of the part of the electromagnetic spectrum that cannot be seen by humans or any other biological eye.

Then, are not radio waves or radio beams comprised of ‘photons’, just like visible light??

Sorting out  the difference between light (or radio) waves and light (or radio) particles hurts my head so this is how I finally reconciled it.

 

Light (and Radio) have properties of BOTH particles and waves.  You can measure either property but the wave property is easer to measure with radio and the particle property is easer to measure with light.

Everything that radiates in the electromagnetic spectrum radiates photons.  There is no difference in the weightless particles.  The difference is the frequency that they vibrate at.  That frequency that the photon vibrates at represents the “energy level” of the photon.  The higher the frequency the higher the energy level.

Thank you for reply.

 

I will rephrase my question. Are visible-light/beams  and radio-waves/beams composed of the same sub-atomic particles called as photons?
