I think I've answered it: It is impossible to create or destroy matter. In a vacuum, electromagentic waves will dissipate, but not completely disappear (they will reduce to an infinetly small amount, but will never reach 0). Particles in space deflect and scatter the waves, and the deflected energy continues to travel, just in a different direction. But no matter what, some of the energy will continue to travel in the original direction. Therefore, remnants of the waves would travel indefinetly in the original direction. If I'm correct, this means that it is possible for radio waves, however small, to travel for 5 billion years. Now the maths: 5 000 000 000 years = 157 680 000 000 000 000 seconds
Speed of light = 299 792 458 metres per second 157 680 000 000 000 000 * 299 792 458 = 47 271 274 777 440 000 000 000 000
Therefore in 5 billion years, the radio waves would travel: 47 271 274 777 440 000 000 000 000 metres
47 271 274 777 440 000 000 000 kilometres

Which type of wave travels faster gamma or radio?
The same. Both are electromagnetic waves; in a vacuum, they both travel at the speed of light.
What term is used to describe the collection that includes gamma rays x-rays ultraviolet light visible light infrared radiation and radio waves?
All travel at the same speed through a vacuum
What speed do radio waves travel in air?
Radio waves, microwaves, infrared, visible light, ultra violet, XRays, and gamma rays are all part of the "electromagnetic spectrum". They are all electromagnetic radiation and they all travel at the speed of light (186,000 miles per second). The only difference between them is their frequencies (or wavelengths)
Can visible light travel faster in a vacuum than both xrays and radio waves?
No. We call it the "speed of light", but it's also the speed of radio, X-rays, heat, ultraviolet, microwave, gamma rays, etc, and all forms of electromagnetic radiation travel at the same speed, as long as they're in the same medium (vacuum or material substance).
Is the speed of a radio wave in a vacuum greater than the speed of a gamma ray?
No. The speed of all electromagnetic radiation is the same in vacuum, from the longest radio wave to the shortest gamma wave.
Electromagnetic waves can travel through a?
Vacuum
Which can travel through a vacuum?
Electromagnetic waves.
Do microwave travel through vacuum?
Yes, any electromagnetic wave can travel through a vacuum.
Is it possible for a electromagnetic wave to travel through a vacuum?
yes, they can travel.
Do infrared waves travel through a vacuum?
Yes, infrared waves are part of the electromagnetic radiation spectrum and all electromagnetic radiation will propagate through a vacuum.
Is it true that unlike mechanical waves electromagnetic waves can travel through a vacuum such as you would find in space?
Correct, electromagnetic waves can travel through a vacuum. Sunlight is an example of this.
What Waves that can travel through a vacuum?
Electromagnetic waves.
What kind of energy can travel through a vacuum?
electromagnetic energy
What kind of wave can travel through vacuum?
Electromagnetic waves.
Can microwave travel through vacuum?
A microwave is near the "red" side of the electromagnetic scale. All electromagnetic travels at the same rate. Light is a form of electromagnetic radiation which travels through a vacuum (space). Thereofore, being a part of electormagnetic radiation, microwaves will travel through a vacuum.
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.
Can mechanical waves travel through any type of medium?
Yes, except vacuum. Only Electromagnetic waves can travel through vacuum.
