Hi, is it correct to say that one of the uses of UV light is that it can be used in:
-Neon signs in billboards
-Fluorescent lamps?
The question is for 2 marks.
Would I get both marks for these 2 points?

TBH I'm not totally sure. I always thought the main uses of UV light was for Sun Tans and detecting forged bank notes, but it is used in both of your answers, so, yes, you probably would get 2 marks. But don't quote me on it ;)

Aren't Neon signs made of Neon? at least that's what I studied.
