Why, when I go to an area that is blocked from radio signal, does my radio receive and/or output white noise or static instead of cutting out?
In: Technology
When you tune a radio to a specific channel, it’s like telling it to only look for one “*color*” of radio wave. When music is coming through it’s like a radio station is flashing a light of that color in a way that will make the magnets in your speakers vibrate as if that song was being played right next to them.
When you’re close enough to the radio station that it’s light is brighter than any other of that color, other sources of that color get drown out. Like how you can’t see any stars when the sun is out.
When you’re far enough away that the light from one radio station is no brighter than another, your radio starts to get signals at random from any photon that happens to have the same “color” as the station you were tuned to. So, the magnet in your speakers starts to vibrate at random, and viola white noise.
