WebThe speed of light in vacuum is constant and does not depend on characteristics of the wave (e.g. its frequency, polarization, etc). In other words, in vacuum blue and red colored light travel at the same speed c. The propagation of light in a medium involves complex interactions between the wave and the material through which it travels. WebWhen the fields are wiggling about 500,000,000,000,000 times every second, your eye sees red light. If your eye looks at fields which are wiggling about twice that fast, or about 1,000,000,000,000,000 every second, the light looks blue. All of the colors of the rainbow are due to the fields wiggling at slightly different rates.
