Light is an electromagnetic wave that consists of tiny particles called photons this wave electrical origin and have the ability to travel through a vacuum as they do not require a material medium for propagation.So heat and light from the sun reach through a vacuum.If they required a medium they would never reach us across the empty space!!

What can travel through space?
the waves are too small to interact with any medium other things that are unusually dense, photonic light and electronic light (used in electron telescopes) go in between air molecules
How far can sound travel in space between astonauts?
Sound waves require a medium to travel through to propagate from point A to point B. In space there is no such medium, so sound does not travel in space.
Can you hear anything in outer space?
No. Sound requires a medium through which it can travel. Since space is near a vacuum, there is no medium for sound.
What happens when you yell in space?
Sound won't travel in space because it has no medium to go through.
Why is it impossible for sound to travel through outer space?
In outer space there is no air medium for travelling of sound waves.so it is impossible for sound to travel through outer space ..!!
What can travel though space without a medium?
Light, radiation, radio waves.
What can travel through space without a(n) medium?
Electromagnetic waves can travel through space without a medium.
Sound needs a medium for traveling?
Sound waves cannot travel without a medium. Therefore, any big explosions in space cannot be heard. Light waves can travel without a medium.
Can a tranverse wave propogate without a medium?
light travels as a transverse wave and it can travel without any medium as it does while travelling in space.
Does light need a medium through which to travel?
No, it does not. It can travel through any open space. Sound, unlike light, needs a medium to travel. So light can travel through outer space but sound cannot because there is no medium.
Does light waves travel fastest through empty space?
Light waves, like all electromagnetic waves, travel without a medium, so they can travel through empty space. Sound waves, on the other hand, do require a medium to travel or propagate; therefore, they can not travel through empty space.
Does light require a medium to travel through?
No, light doesn't need a physical medium, like air, to travel. As a matter of fact, light travels the fastest it possibly can, 2.98 * 10^8 meters per second, in a vacuum, like space. If light couldn't travel without a medium, then Earth wouldn't receive any light from the Sun.
What type of wave requires no medium to travel through?
Waves need not require medium to travel through. Only Mechanical waves like sound waves require medium to travel through. Electromagnetic waves travel in vaccum like light waves. Some waves transmitted in a medium due to disturbances in the medium .
Do Light Waves Require Mediums?
Light waves can travel through empty space. You might say that the empty space is the medium in this case.
Where can electromagntic waves travel through?
Electromagnetic Waves can travel through space without any material medium.
Due mechanical waves need a medium to travel through?
Yes, mechanical waves do need a medium in order to travel. Other waves, such as light, do not (thus they can travel through space).
Is it true that speed of light changes with medium?
Yes. The speed of light in a vacuum (or space) is 3x10^8 m/s. Light will travel slower in any other medium.
