Detailed explanation-1: -Gamma rays have the highest energies and shortest wavelengths on the electromagnetic spectrum.
Detailed explanation-2: -Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum. We call this the “speed of light"; nothing can move faster than the speed of light.
Detailed explanation-3: -The radio waves would have a lower energy and would travel slower than gamma rays.
Detailed explanation-4: -Scientists find that bursts of gamma rays may exceed the speed of light and cause time-reversibility. Credit: DESY, Science Communication Lab (used with permission by Astronomy Picture of the Day, which is co-managed by Robert Nemiroff at Michigan Tech).
