Aopprox. 300,000,000 meters (186,282 miles) per second, in vacuum.
Slightly less in material media.
That can be light, or some other electromagnetic wave (light is an electromagnetic wave), or gravitational waves.
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.
Light is an electromagnetic wave. Electromagnetic waves travel at the speed of light. Electric and magnetic waves don't travel on their own - the wave travels as a combined electric and magnetic wave.
All electromagnetic waves travel at the same speed in vacuum.
The light wave, which is electromagnetic energy, is the fastest wave. The speed of light, which is a physics constant, is the speed of light in a vacuum, and no object with mass can be accelerated to this speed.
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 30,000 kilometers per second! So, it goes really fast.
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.

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.

Yes. The light is an example of a electromagnetic wave and its speed is constant.
