Light
Does the speed of a photon go to zero when it reflects of a mirror at a 90 degree angle? Just to be sure, I mean if the photons’ comes straight down on a mirror lying flat and reflects straight up, does the photon’s velocity reach zero at any point in time?
also
Particle accelerators:
If the particles travel in a circle at 99.99% of light why do they have to be built so big? Couldn’t they just travel in circles until the distance needed is reached?
