Ive been seeing a lot lately on the dangers of 5g and exposure to the internet and mobile signals but I dont understand why they are considered harmful when the 5g frequency band will be around 25 Ghz. Visible light has a frequency much much greater than this, and I thought how damaging radiation is, depends on its frequency. Ionising radiation is several orders of magnitude greater in frequency.
Just wanted to know if there was any physics behind the 5g signals impact on the human body.
