In the 5th chapter of my story called Life on Kepler Bb, Alma wants to discover her superpowers besides x ray vision and micro vision. Robin builds a pair of radios so that they can talk to each other over long distances.
The radio works like this:
A tiny microphone picks up the sound waves and converts them into electricity. That electricity then gets converted in UV light via a signal transducer. UV light then travels through everything it can including glass until it reaches the signal receiver on the other radio. The signal receiver converts light back into electricity and last but not least the electricity reaches the speaker and gets converted into sound.
The humanoids in my story(at least the species I am talking about since there may be other species in my story) are immune to UV light and can't see it. They can still get sunburnt(Or should I say starburnt since the star that Kepler Bb is orbiting around is not our sun? But then again the definition of sun is a star or group of stars that has at least 1 planet orbiting around it), just not from UV light.
But how efficient would this UV signal be over a long distance? High energy photons tend to loose energy much faster than low energy photons so UV would lose energy faster than IR or even visible light would. Loosing energy could mean loosing data after x distance units(I say distance units because it might be a unit that isn't used here on earth for distance). Loosing data would also mean loosing some letters or words if it is converted into sound or worse, jumbled up code. Also the UV light can go through more things than visible light or IR but not everything. It can't go through bone so unless Alma is holding the radio right the signal will be blocked by her bones.
