What else can I help you with?
What is an empty space that contains no matter that light can travel through?
A vacuum.
In a perfect vacuum, light waves travel at 300,000 kilometers every second. When light waves travel through materials, such as air, they?
slow down.
The speed of light indicates how fast light can travel in a vacuum?
Yes ... in a vacuum.
What do light waves travel best through?
Light waves travel fastest through vacuum, at nearly 30 million meters per second. Light travels more slowly through other substances such as air and water, and can be absorbed.
What type of wave does not need a medium to travel through?
It is electromagnetic radiation that needs no medium to travel in. Gamma rays, light and radio waves, all forms of electromagnetic radiation, can travel through the vacuum of space very well. In fact, they prefer it.
Why doesn't light travel through a vacuum?
Light does travel through a vacuum.
Can gases travel through a vacuum?
No. Only light waves can travel through a vacuum.
Is vacuum a medium of light?
Light can travel through vacuum, but it is not a medium.
Does light travel at its slowest speed when passing through a vacuum?
No, light is at its fastest in a vacuum.
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.
What term indicate through which light does not really travel?
A vacuum is the term that indicates through which light does not really travel.
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.
Can polarized light travel through a vacuum?
Why not? Of course it can!
Can light and sound travel through vacuum?
Light can. Sound can't.
What does light travel faster through?
Light travels faster through a vacuum than through any other medium, such as air, water, or glass. In a vacuum, light can travel at its maximum speed of approximately 299,792 kilometers per second.
