I noticed this phenomenon once when I was still in high school. I was listening to the radio and there was a real bad storm brewing outside. So the reception wasn’t too good. And yet, just by chance, I noticed when I stood in one particular spot in the room, the radio reception improved! Was I just imagining it? Or was it just coincidence? I did it a couple times to verify.
P.S. Sorry about the blank post. But I submitted it the right way and yet my text didn’t appear until I readded it just now. (Talk about strange phenomenon.)
Have you ever noticed that when you’re driving slowly in your car, such as approaching the last few feet of a red light, that the reception fades in and out? The FM radio waves bounce off of nearby buildings and bridges, creating a pattern of peaks and valleys in the strength of the signal. It’s called multipath distortion. If you stop in a low point, you can usually improve it by moving by half a wavelength, which in the case of FM radio would be about 5 feet.
