Electromagnetic waves travel through a vacuum at the speed of light. Whether that electromagnetic wave is a radio wave, a microwave, light, an X-ray or a gamma ray, it will move through a vacuum at a fixed speed -- the speed of light. We use c to indicate this speed, and it's about 186,282 miles per second, or exactly 299,792,458 meters per second. A link can be found below for more information.
All electromagnetic waves travel at the speed of light, which is approximately 299,792 kilometers per second in a vacuum.
Electromagnetic waves travel at the speed of light in a vacuum, which is approximately 186,282 miles per second.
Radio signals travel at the speed of light, which is the fastest speed possible for electromagnetic waves. This means that radio signals travel at the same speed as other forms of electromagnetic waves, such as visible light and X-rays.
Radio waves travel at the speed of light, which is the fastest speed possible for any form of electromagnetic radiation.
Electromagnetic waves in vacuum move about 881 thousand timesas fast as sound in sea-level air.

They travel at the same speed of light that is 299,792,458 msec-1
Electromagnetic waves are waves which can travel through the vacuum of outer space.
Electromagnetic waves in vacuum move about 881 thousand timesas fast as sound in sea-level air.
The biggest difference is that mechanical waves require a medium to travel through and electromagnetic waves do not.
All electromagnetic waves travel through space at the "speed of light". Light is one form of electromagnetic waves.
Electric and magnetic waves, or electromagnetic waves, travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second.
