emits radio wave photon.
The antenna should be parallel to the electrostatic field of the wave, and perpendicular to its magnetic field and to its direction of propagation.

RAdio Detecting And Ranging
1) Any object that emits radiation (because of its temperature) will emit in all wavelengths, including visible light, infrared, radio waves, ultra-violet, etc.What changes is the proportion of each (which depends directly on the temperature).2) The Earth's atmosphere is transparent to radio waves (meaning: it is easy to receive radio waves from space -- in general they are not blocked by the atmosphere).3) It is easy to build a receiver that gives us the direction from which the radio waves are coming. We can draw maps of radio sources (the same way that taking pictures in visible light lets us draw maps of the visible stars).
yes they are coming to lebanon to radio one

Your radio separates the stations according to their frequency (wavelength).
