As invisible as radio signals then.

Now now... Let's be fair...

Radio broadcasts to everyone.

Light you can block off to a single direction.

Oh wait, directional radio antennas exist. Nevermind, yes. Exactly like radio waves.

    Sorta, kinda. You're really only just attenuating things a lot. It's tricky to actually block it off fully.

    Same with radio waves, as light is literally the same phenomena as radio waves, it's just shaking faster.
