The quickest, easiest, most reliable way to find it is
to consult a reference book or website.
There you will find the number:
299,792,458 meters per second.

In a vacuum, all electromagnetic waves have the same speed: about 300,000 kilometers per second.In a vacuum, all electromagnetic waves have the same speed: about 300,000 kilometers per second.In a vacuum, all electromagnetic waves have the same speed: about 300,000 kilometers per second.In a vacuum, all electromagnetic waves have the same speed: about 300,000 kilometers per second.
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.
All electromagnetic waves travel at the same speed in vacuum.
In a vacuum, the speed of an electromagnetic wave, such as light, is constant at approximately 299,792 kilometers per second (or about 186,282 miles per second). This speed is denoted by the symbol 'c' and is a fundamental constant of nature.
The speed of an electromagnetic wave is determined by the properties of the medium it is traveling through. In a vacuum, electromagnetic waves travel at the speed of light, which is approximately 299,792 kilometers per second. This speed can change when the wave enters a different medium.

In a vacuum, any electromagnetic wave will move at the "speed of light", which is about 300,000 km/second.

No. The speed of all electromagnetic radiation is the same in vacuum, from the longest radio wave to the shortest gamma wave.

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.
Light can be considered as a wave, or as a particle. As a particle, the particles are called photons. As a wave, light is an electromagnetic wave. In either case, the speed of light (in a vacuum) is approximately 300,000 km/sec.
