[QUOTE="person123, post: 6436606, member: 611120"] [B]TL;DR Summary:[/B] An idea (which is likely not feasible) for measuring the speed of light using spinning mirrors with a laser and camera attached Hi. This is an idea which I just happened to think of, and I was curious if it would be at all feasible. Here's a quick sketch I drew: [ATTACH type="full" width="352px"]275283[/ATTACH] The two curved mirrors should have a laser attached on one end and a video camera attached on the other. The laser would be tilted very slightly above horizontal (much less than shown in the sketch), so the light bounces up the mirrors and exits on the other side. I would imagine that the camera would pick up a vertical line of light. The mirrors should then be spun rapidly (with the laser and camera spinning with them). I would imagine that, because it takes time for the light to travel up the mirror, the line of light which the camera picks up on would be shifted very slightly horizontally. To measure the speed of light, you would have to know the tilt of the laser, the radius of the mirrors, the height of the mirrors, and the speed the mirrors are spinning. Would this be at all possible? Thank you! [/QUOTE]
