Radio waves are just " less powerful" than visable light Its interesting that radiowaves permeate all space within say 50 miles except farraday cages, we think so atleastSo maybe a flashlight permeates all space within 100 miles maybe

Lambda = v/f lambda being wavelength; v is speed of light and f is frequency.So if frequency of visible light is 10000 times that of microwaves...Vf = lamba youd need to change the frequency of light by ten thousand by my reckoning. Fuck knows how. Or why
