How fast do all electromagnetic waves travel?

Electromagnetic radiation is a type of energy that is commonly known as light. 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.

Electromagnetic travel at about the same speed as light travels through waves, so it would be about 30.*10^8
