# Would not the oscillation of light slow down the wave? [duplicate]

Would not the oscillation of the light wave slow down the wave? Does light travel at "c" of its net position over time, or does it travel at "c" on the wave?

The beam advances at the speed of light $$c$$, but there is nothing that is waving around it as it advances. So there is no conflict with the statement that $$c$$ is the maximum speed.
