... speed in a perfect vacuum.
In vacuum, and very nearly the same in all common media.
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.
They are all transverse waves and travel at the same speed in a vacuum.
Yes it is. It's the speed we call the "speed of light", although it applies equally to electromagnetic radiation at all frequencies/wavelengths.
the speed of lightspeed of light
All electromagnetic waves travel at the same speed in a vacuum -- the speed of light.
No. The speed is THE SAME for all frequencies of electromagnetic waves.

No. Gamma rays and radio waves are both electromagnetic waves and travel at the same speed. They just have different wavelengths/frequencies.
the speed of lightspeed of light
All electromagnetic waves travel at the same speed in a vacuum -- the speed of light.
They travel faster
Yes. The light is an example of a electromagnetic wave and its speed is constant.
They are all basically the same thing, electromagnetic radiation, but with different frequencies. All these waves are em waves which travel with the speed of light and it is the common b/w all the waves.
Electromagnetic energy travels at c, the speed of light. The speed of light, c, is 299,729,458m/s
