Perhaps you have heard of the "speed of light" ?
Light is an electromagnetic wave, and its speed is the speed of all forms of electromagnetic radiation.
That speed is 186,282 miles (299,792 km) per second in vacuum, slightly less in any material medium.
it depends on how the motion got started and what forces are acting. but for electromagnetic radiation, it only has one speed - the speed of light - no matter what frequency or wavelength or intensity of the radiation.
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.
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.
