Electromagnetic radiation is throughout us , but we’re largely unaware that bodies are constantly bathed in waves of the stuff because our eyes aren’t equipped to peer it. Dr. Gregory Chavat decided to offer us a glimpse of an EM waveform, however, by utilizing a coffee can radar system, just a few LEDs, and long-exposure photography. The setup consisted of a radar emitter comprised of one coffee can and a second can with a number of LEDs attached to function a tethered receiver antenna. Those LEDs were then set to that remove darkness from red or green to light up the EM wave peaks and valleys. By moving the receiver closer and extra far from the emitter while taking an extended exposure photo, the nice doctor was in a position to capture the wavefront radiating on film, and allow you to see the unseen with slightly Christmas-colored flair. Check the video below for a fuller explanation, and hit the more coverage link to benefit the right way to build a coffee-can radar and perform some basement black magic yourself.
