300,000,000 metres per second.
Light waves travel from 100 million kilometers through nearly space. Electromagnetic waves do not require a medium or a type of carrying source. Around 300 km around the atmosphere and 10 m in the water.

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.
What is the electromagnetic wave which has longest wave length?
There is no maximum wavelength.
How do you know the speed of a 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.

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.
How does the speed of a photon compare with the speed of an electromagnetic wave?
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.

What is the electromagnetic wave which has longest wave length?
There is no maximum wavelength.
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.
How do you solve for the speed of of an electromagnetic wave?
The speed of an electromagnetic wave is 30,000 kilometers per second! So, it goes really fast.

Energy that travels at speed of light?
That can be light, or some other electromagnetic wave (light is an electromagnetic wave), or gravitational waves.
What Effect electromagnetic wave is bent as it passes from one material into another?
That is related to the speed of the electromagnetic wave in the material.

What kind of Wave is an electromagnetic wave how fast does it travel?
An electromagnetic wave is a wave with electric component and magnetic component. In free space (vacuum), an electromagnetic wave travels with the speed of light, that is 3x10^8 m/s. In fact, light is also an electromagnetic wave.
Do electromagnetic waves travel at the same speed in a vacuum?
Yes. The light is an example of a electromagnetic wave and its speed is constant.
