# How does radio wave get reflected?

Actually recently I posted a question in h-bar ($$\hbar$$) relates to radio wave reflection from mirror, and one of the user replied that it can't, only ionosphere can reflect it, so my question what is the general phenomenon of different frequency em wave reflection? How does ionosphere able to reflect those wave? Do we see similar phenomenon when dealing with outer space? I am not a physicist so answering this question s in not in my reach although I tried some research but that does not yield Anything, any help will be appreciate d

• Many people have radio reflecting telescopes attached to the sides of their houses, aimed at geostationary satellites, sending their observational data to a decoder in their television set.

Similar thing happens when a wave is incident onto a dielectric media, but in this case it is only partially reflected and partially transmitted into the media (i.e., not fully screened.) The phenomenon is purely classical - $$\hbar$$ is not involved.
