Distances between radios: Miles: 6 Feet: 31,600 (approx.) Speed of Radio Waves: Almost the speed of light (roughly 187,000 miles/second) *Of course, various obstacles and air affect this speed greatly* It would take a sound wave traveling at roughly 760 mph (or approx. 1,114 feet/second) at least 30 seconds or so to cross the 6 miles of distance. If you were somehow able to yell loud enough to be heard from 6 miles while transmitting the radio signal at the same time, the receiver would hear the radio transmission almost instantly and afterwards, hear the original sound wave half a minute later. But save yourself some breath and test it out when standing only a few hundred feet away from your friend while transmitting; you can still hear latency! Chad and I also did some tests while talking over the radios and our cell phones at the same time. The radio signals were received and heard first because they traveled through the air directly from one radio to the other, as my cell phones microwaves had to first travel to a cell tower and then be relayed to Chads phone. You could hear the latency and it was kind of cool :) My radio wave ----> Chads Radio My cell phones signal ----> Cell Tower -----> Chads Phone The reason these experiments fascinate me is because it shows that every event in our universe, no matter how instantaneous they may seem, do take time to occur. Youd think a sound wave is pretty speedy but compared to electromagnetic waves they are stupidly slow. This is a video I hastily put together in one night but I do plan on making more legitimate videos on my radio ventures in the future.
