I would love to watch this person glaze over while I explain that they both run at 2.4 ghz and are thus identical as far as radiation goes. The EM spectrum isn’t that complicated a concept, I don’t know why it’s such black magic to so many
It's not second semester physics, though. It's like middle school nature & science class. It's part of understanding the base foundations of our modern world.
Not to mention, we've known about and actively used electromagnetic waves since the invention of radio (if we ignore light bulbs and visible light, of course)
I know someone that would use a microwave to heat up food.
But would literally run away from it whenever she used it and only come back after the set time passed.
That is at least somewhat logical, if not a bit overly paranoid. A microwave can cause damage if the shielding is damaged, wifi cant ever cause damage.
Most microwaves (especially old ones) are shielded very poorly. However microwave radiation is nonionizing so the only harm it is going to do to you is burns if you get hit by enough of it. Needless to say you aren't going to get hit by that much no matter how poorly shielded your microwave is. The worst any consumer microwave will do is screw up your wifi reception around it.
