It travels at the "speed of light". In vacuum, that's 299,792,458 meters per second.
In any kind of material substance, it's less. How much less depends on the
individual substance ... they're all different.

300,000 km/second, equivalent to 300 million meters/second.
That speed is known as the "speed of light".

Is a measure of the speed at which water can travel through porous soil or bedrock?
permeability......?
How fast do ultraviolet waves travel?
the speed of light = 299 792 458 m / s
Does thunder come before lightning?
Yes; light travels faster than sound. Sound is vibrational mechanical energy that propagates through matter as a wave and light, or visible light, is electromagnetic radiation of a wavelength that is visible to the human eye. Sound must travel through matter to be perceived by the human ear. Light does NOT.
How fast does sound travel through oxygen and nitrogen?
767mph, 1235km/h, 1125ft/s, 343m/s (these are all different measurements of the same speed.)
How have seismic wave studies helped scientists determine the structure of Earth's interior?
The speed of the waves that travel through the interior can tell the density of each layer of the Earth. Some waves can make it through certain layers, but not others.
What are waves that travel through space at the speed of light called?
All electromagnetic waves travel through space at the "speed of light". Light is one form of electromagnetic waves.
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.
Do electromagnetic waves all travel at the same speed through space?
Through a vacuum ... yes. Through outer space, which is not quite a vacuum ... not quite, but very very close.
How fast do waves travel through space?
all electromagnetic waves travel at the same speed through space. This is the speed of light, or 300 000 000 m/s (3x108 m/s).
Do the waves of the electromagnetic spectrum travel at the same speed through space?
Yes. It's usually called the "speed of light", but it's actually the speed of all electromagnetic phenomena.
What speed do electromagnetic energy travel through space?
186,000 miles or 300,000,000 meters per second. The speed of light.
Who discovered that electromagnetic waves can travel through empty space at the speed of light?
James Clerk Maxwell.
What form of energy can travel through space at the speed of light?
(a) Electromagnetic waves; that includes light. (b) Gravity waves.
By which process does starlight travel though space?
In the form of electromagnetic waves through free space at the speed of light 3 x 108 m/s
Will electromagnetic radiation with a longer wave length travel through space slower than one with a shorter wave length?
The speed of electromagnetic radiation stays constant at a speed of 299,792,458 metres per second.
What is true of electromagnetic waves?
For instance, the fact that in a vacuum, it moves at the speed of light.For more information about electromagnetic waves, you may want to check (for example) the Wikipedia article about electromagnetic waves.
A general term to describe all waves that can travel through empty space?
The only waves that are known and proven to travel through empty space are electromagnetic waves. Theoretical gravitational waves also travel through empty space but have not yet been proven to exist. Both electromagnetic and gravitational waves move at the speed of light, thus it could be argued that a general term to describe all waves that can travel through empty space are waves that move at the speed of light.They say the message is the medium. In this case you could call it the "Ether". Ether is a blanket term describing information that is transmitted by any source through any medium. In this case the emptiness of space.
