The speed of an electromagnetic wave is 30,000 kilometers per second! So, it goes really fast.
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.
In a vacuum, any electromagnetic wave will move at the "speed of light", which is about 300,000 km/second.
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.
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.
frequency. The speed of an electromagnetic wave is constant and is determined by the medium it travels through.
The formula to solve wave speed is: wave speed (v) = frequency (f) x wavelength (λ). It represents the speed at which a wave travels through a medium.
That is related to the speed of the electromagnetic wave in the material.
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.

All electromagnetic waves travel at the same speed.
You need to know it speed, wavelenght and its frequency.
