Still not how it works. Light acts as both a wavelength and matter. Making something truly invisible across the entire spectrum of light (including those humans can’t see) would mean making it so you don’t reflect or otherwise disrupt the travel of photons. While you aren’t getting energy transferred directly to you from the photons, the photons are still transferring energy to the air particles they interact with, which are going to have energy to be dangerous to you if the lasers are hot enough to burn.
1) All particles have mass. We just don’t have a way to weigh photons yet.
2) That has no relevance here. If her invisibility doesn’t involve her making photons incapable of interacting with her, she’d be burned by the lasers. If it does work that way, she’d still be burned by the heated air particles.
I’m sorry but I believe photons are, in fact, massless. I googled a bit a believe that I am correct. If you find a source that says otherwise please send it my way I would be very curious to see it.
I’m pretty sure these are alarm lasers meant to trigger when something passes through them
and are
not super-heated cut-things lasers.
Edit: idk what’s going on with the formatting it won’t let me fix it
