WebWhen light of different wavelengths, or colors, travels through any medium other than vacuum, it travels at different speeds. In glass, red light travels faster than blue light. Is it true that all light travels at the same speed? Light travels in waves, and electromagnetic radiation travels through a vacuum at the same speed, which is about 3. ... 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.
