Moving lights and mirrors.
A particle of light was given off with the speed, 300,000,000 m/s from a certain mirror. As it hits the other mirror, it will bounce off again to reach the first mirror and vice-versa. The process repeats infinitely. We can assume that the two mirrors are face to face and the particle of light does not lose any speed in each bounce/reflection. Given that the two mirrors are moving apart with the speed of 100m/s and their initial distance within each other is 50m, what is the distance traveled by the particle of light after 10s?
