    Does inverse square law apply to light in vacuum?

    Thanks. I tried to google but I couldn't confirm it, and Wikipedia does not mention it in either "photon" or "light" articles. Would you know what should I google for so I can find some references about it?

    Just went there for the picture, and was stupid enough not to read it. Funny!

    Please note that if you took something from another source, you must attribute it to that source, or else you are stealing something! Worse still, some of these things might be copyrighted, and WE might get into a whole of trouble without making at least proper references to the sources.

    Besides, it is just good practice (and manners) to give credit where credit it due.
