Turntable Wall Mounts
A laser pointer is mounted on a turntable. The turntable is set to rotate at 10 revolutions per second.?
A cylindrical wall is set around the appliance. a. How far the laser pointer should be the wall so that the point from the pointer to travel at the speed of light? B. If the wall is dismantled and built again at twice the distance of the unit, how fast it feels to travel instead of laser pointer? c. In part b, above, if the wall is made of a cylindrical mirror and I'm in the position of the device, I see a light that travels faster than the speed of light? If so, how can this be? If not, why not and what I see? The whole experiment was established in the gap so that there is no or very little) degradation (of laser light. Imagine looking into the sky at night and see a light that travels through the night sky at a speed faster than the speed of light. "The first reaction will be "How can that be?
EDIT: I made a math error! We have to calculate a circle that is 0.1 of the distance that light travels in 1 second c = 3 * 10 ^ 8 / 10 = 3 * 10 ^ 7 mc = pi * diameter of 3 * 10 ^ 7 m = pi * diameter Ø = 3 * 10 ^ 7 / pi = 0.95 * 10 ^ 7 m = 9.5 * 10 ^ 6 m R = 4.77 * 10 ^ 6 m That's a b Solve the same way. C) The final radio response is twice a. Photons can not travel faster than c, so lets consider a photon that comes out at time 0. EDIT: MISS COPY The photon travels a 4.77 * 10 ^ 6 feet away in c ===> speed = time * 4.77 * 10 ^ 6 = 3 * 10 ^ 8 * tt = 1.59 * 10 ^ (6 – 
t = 1.59 * 10 ^ -2 s ===> photon hits the wall at t = 0.0159 s reflected. Travel making around the same time. ====> You see the photons that left 2 * 0.0159 = 0.0318 s ago. The point has no mass ===> The point may seem to move at a faster than c. Consider a machine gun that fires 1,000 rounds per minute at 500 m / s cooking in a circle of targets to 1000 meters. The weapon spins at 1 revolution minute. How quickly the bullet holes move through the objectives? Does the speed with which the weapon turn affect the speed of bullets?
