In a vacuum, light always travels at the same speed, about 300 000 kilometers per second.
Light does travel through a vacuum.
When light travels through anything that is not a vacuum, it will usually slow down.
No. Only light waves can travel through a vacuum.
No, a vacuum is the absence of any medium, including air. Light can travel through a vacuum because it does not require a medium to propagate.
No, light is at its fastest in 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.
it travels at c (speed of light in a vacuum)
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.
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.
A vacuum is the term that indicates through which light does not really travel.
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.
Why not? Of course it can!
