What evidence do we have that light travel through a vacuum?

You create a vacuum in a lab, and then shine a light through it, and there is experimental proof that light travels through a vacuum. Alternatively, take the fact that light travels through space - if light could not travel through a vacuum, no light from the stars, the moon or the sun would ever reach our planet.

What materials can light travel through faster than it travels through air?

Light can travel faster through a vacuum than through air. In a vacuum, light travels at its maximum speed of about 299,792 kilometers per second. This is because there are no particles in a vacuum to slow down the light's speed.


Does light travels through vacuum by radiation?

Yes, light can travel through a vacuum via electromagnetic radiation. In a vacuum, light does not need a medium to propagate because it consists of electromagnetic waves that can travel through empty space.

Will a light wave travel through a vacuum?

Yes, light can travel through a vacuum because it consists of electromagnetic waves that do not require a medium to propagate through. This is why light from the sun and other stars can reach us despite the vacuum of space.
