- burgerbrain 16y agoYou didn't pay very close attention in physics class did you? Millimeter wavelength electromagnetic waves are still radiation as much as any other wavelength.
- mrkurt 16y agoErm, I shoulda said "xray". My mistake. :)
- Locke1689 16y agoSo? If you think that all parts of the EM spectrum have the same effect then you didn't pay very close attention in physics class. Propping up pseudoscience bullshit like "it's radiation!" is the same reason why we have to deal with morons complaining about wifi signal. Ugh /former physics minor
- burgerbrain 16y ago>think that all parts of the EM spectrum have the same effect Absolutely nowhere did I indicate that. It does use radiation, and radiation is for the most part, and in this case, completely harmless. I would assert that not understanding that all EM waves are radiation, including visible light, is the reason we have to deal with morons complaining about wifi signals. /former physics major, and current title dropper
- Locke1689 16y agoFor better or worse, the word "radiation" carries a negative connotation. It bugs me when people who know better throw the word around knowing that they exploit people's ignorance. Of course people not understanding that all EM is radiation is a problem but the statement that "it is a problem because people don't understand x" is true for almost every value of x.
