The speed of all electromagnetic waves is 299,792,458 meters per second in vacuum, and
somewhat less in any material medium. How much less depends on the specific material.

How do you know the speed of an electromagnetic wave in a vacuum?
The speed of electromagnetic waves in a vacuum is the same as the speed of light (which is, in itself an electromagnetic wave). It can be measured by finding the frequency and wavelength of two different waves, and then by that correlation, the speed of the waveform.
Why does an electromagnetic wave in space never slow down?
In empty space, an electromagnetic wave can only travel at one speed - the speed of light.In empty space, an electromagnetic wave can only travel at one speed - the speed of light.In empty space, an electromagnetic wave can only travel at one speed - the speed of light.In empty space, an electromagnetic wave can only travel at one speed - the speed of light.
Why does a vacuum and a electromagnetic wave travels the same speed?
A vacuum doesn't travel. All electromagnetic wavestravel at the same speed in vacuum.
What is the fastest that an electromagnetic wave can travel?
The fastest that an electromagnetic wave can travel is 299,792,458 meters per second.That's the "speed of light" ... and all other electromagnetic radiation ... in vacuum.
Which kind of electromagnetic wave travels fastest in a vacum?
All electromagnetic waves travel at the same speed in vacuum.
How are all electromagnetic wave alike?
All electromagnetic waves travel at the same speed.
In a vacuum all electromagnetic wave have the same?

Why does light have a speed?
Light is an electromagnetic wave and, like all waves, it has a speed.

A vacuum doesn't travel. All electromagnetic wavestravel at the same speed in vacuum.
Which light wave has the fastest speed?
All electromagnetic waves travel at the same speed in vacuum.
What is the speed of any electromagnetic wave?
In a vacuum, any electromagnetic wave will move at the "speed of light", which is about 300,000 km/second.
What is the fastest that an electromagnetic wave can travel?

Which kind of electromagnetic wave travels fastest in a vacum?
All electromagnetic waves travel at the same speed in vacuum.
Is the speed of a radio wave in a vacuum greater than the speed of a gamma ray?
No. The speed of all electromagnetic radiation is the same in vacuum, from the longest radio wave to the shortest gamma wave.
