We all know that light speed in a vacuum is constant and travels 9.8 X 1018 meters in a year. Now since light travels in waves instead of a straight line, if the wave was then uncurved, it would cover more distance than when it was in its original state. Of course different lights have different frequencies so a wave with a higer frequency must cover more ground than waves of lower frequencies like red. But if a radiowave was put next to a lightwave and both where pointed to the same destination, based on the Einstein's constant rule, both will hit the wall at the same time. My questions is, is the higher frequency wave faster than the lower frequency wave since it had to cover more distance to hit the same destination at the same time? Does this mean that the speed of light is different at each frequency?
