One of the more useful, and even lifesaving uses of radio waves is weather tracking. We're also getting ticketed for speeding, heating water for tea, and curing timber all with the help of radio waves. The next thing you know we are scanning the skies for clouds and rain, probing the depths of our oceans to get topographical maps, creating pictures of distant astronomical formations, and tracking thousands of airborne objects every second of every day. As early brainiacs learned to make better use of electricity and devices that make use of it they found that something was causing their new toys to act funny.Ĭould it be gremlins, ghosts, aliens, inter-dimensional beings, or some unseen, but naturally occurring force messing up their electrics? Being scientists they opted for the latter and discovered radio waves, then found that radio waves bounced off certain objects at certain frequencies, then found that they could detect the objects that radio waves bounced off of. It's was something just beyond our ability to sense directly. If you want to see how a bit of science has morphed from a laboratory curiosity to something so common we don't even think about it anymore, take a long hard look at radio waves.īack in the 1800s all but a handful of scientist even knew waves of electromagnetic force existed.
