I asked this question in Yahoo Answers but I didn't think that the responses were very good This is just for my own knowledge I wanted to know if let's say for instance that I had a rotary device, clamp right on the center of mass of my phone and it spun rapidly... could the phone spin so fast that it is unable to communicate with radio waves? I don't really know the mechanics/structures of cell phones, for one it doesn't seem like orientation matters in receiving a signal with your cell phones. I am not saying that the radiation pattern of cell phone towers and perhaps the cell phones themselves are circularly polarized rather than linear but anyway... My phone is quite symmetric so assuming that it could spin in excess of something like 3000 rpms which someone told me is actually pretty slow. When doing a test to determine the speed of light, we used interference... well it was a rotating mirror that operated at a varying rpms, even though it was spinning rapidly, the location of the reflected beam was predictable or at least the beam struck the same location enough times for me to count it as "stationary", a dot on a wall for instance. That was a semester ago so I apologize if my terminology is not correct and I haven't been keeping up with my physics lately.
