Well, to be honest, electromagnetic wave itself is never slowed down by anything and travels uniformly at the speed of light, c. However, when you look at macroscopic level, it is possible to slow down a combination of many many electromagnetic waves if they travel though a dense medium. The denser the medium, the more 'radiation' is slowed down. So slowing down process occurs when 'radiation' travels from less dense to more dense medium (the closed atoms are packed together, the more they absorb and reemit electromagnetic waves).
As an electromagnetic wave passes from space to matter, it can be absorbed or scattered by the atoms or molecules in the material. This interaction can result in the wave being slowed down, refracted, or reflected depending on the properties of the material it encounters.
Light is an example of a electromagnetic wave.
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.

That is called a light ray or an electromagnetic wave.

Radio waves are electromagnetic. That's how they can get down here from satellites.

Mexican Wave? A non-electromagnetic wave.
A mechanical wave is not an electromagnetic wave.

When a wire moves up and down repeatedly, it generates an electromagnetic wave. This wave carries energy along the wire and through the surrounding space. The frequency at which the wire moves up and down will determine the frequency of the electromagnetic wave produced.
The wave is called an electromagnetic wave.
