All electromagnetic radiation, regardless of its wavelength, travels at what is called the "speed of light". In a vacuum, it is measured as
- 299,792,458 meters per second.
- 3.0 x 108 meters per second.
- 186,282 miles per second.
Depending on the material and its frequency (or wavelength) it may also be able to travel through other media but at a slower speed than in a vacuum.

the "speed of light" in whatever medium it happens to be. In vacuum,
that's 299,792,458 meters per second.

Which of these is constant for ALL types of electromagnetic radiation in a vacuum?
Answer = Velocity Velocity is the speed of light and, the speed of light, is a constant among Electromagnetic Radiation in the vacuum of space.
Is speed a constant for all types of electromagnetic radiation in space?
Yes it is. It's the speed we call the "speed of light", although it applies equally to electromagnetic radiation at all frequencies/wavelengths.
What do all types electromagnetic radiation have in common?
They travel at the speed of light (c = 3*108 m/s)
Which property is the same for all forms electromagnetic radiation?
The speed (in a vacuum) is the same for all electromagnetic radiation.The speed (in a vacuum) is the same for all electromagnetic radiation.The speed (in a vacuum) is the same for all electromagnetic radiation.The speed (in a vacuum) is the same for all electromagnetic radiation.
The numerical value of the speed of electromagnetic radiation in a vacuum is?
299,792,458 meters (186,282 miles) per second ... the speed of all forms of electromagnetic radiation, including light, in vacuum. The speed is slightly less in air, water, glass, jello, etc.

What does radiation have to do with the speed of light?
All forms of electromagnetic radiation move from place to place at the speed of light.
What do all types electromagnetic radiation have in common?
They travel at the speed of light (c = 3*108 m/s)
Does radio waves always travel the speed of light?
Radio waves, like light, is a form of electromagnetic radiation. Other types of electromagnetic radiation include X-rays, infrared radiation, and gamma rays. All electromagnetic radiation travel at the speed of light.
What is the same for all types electromagnetic radiation?
They all travel at the SPEED OF LIGHT.
Which type of nuclear radiation travels the fastest?
All electromagnetic radiation travels at the same speed. We usually call it "the speed of light" but it's the same for all other forms of electromagnetic waves.
Heat waves traveling at the speed of light are called?
Heat waves traveling at the speed of light are called RADIATION! :)

How fast does an electromagnetic wavelength move?
In a vacuum, all electromagnetic waves/radiation moves at the speed of light (c = 299792458 meters/second). However in matter the speed that electromagnetic waves/radiation moves is reduced by the reciprocal of the index of refraction for that material.
What travles at the speed of light?
All electromagnetic radiation does, and nothing else does.
How fast are electromagnetic radiation?
Electromagnetic radiation travels at the speed of light, or approximately 300,000,000 meters per second.
