# How does the speed of visible light compare with the speed of gamma rays, when both speeds are in a vacuum?

Yes. The Gamma rays ( γ- Rays) are also part of the vast EM radiation, so they also travels with the speed of Light c ($3 x {10}^{8} \frac{m}{s}$). (https://www.quora.com/Do-gamma-rays-travel-as-fast-as-the-speed-of-light)
