Since light cannot travel faster than it does in a vacuum no index of refraction can ever be less than one?
True
What does sound go faster through a vacuum or a solid?
Sound travels faster through a solid than through a vacuum. In a solid, sound waves propagate through the material's molecules, leading to faster transmission. In a vacuum, there are no molecules to transmit sound, so it cannot travel at all.
What is the one thing that cannot travel through a vacuum?
i think voice cannot travel through vacuum.
What medium sound waves travel through?
Sound waves can travel through any matter- liquid, gas or solids. The denser the matter, the faster the sound travels. It cannot travel through vacuum- a vacuum is an absence of matter.
Does light travel faster in a vacuum?
Yes.
How fast can sound travel through a vacuum?
Sound cannot travel through a vacuum.
Do electromagnetic waves travel at the same speed as a vacuum?
They travel faster
Sound cannot travel in?
A vacuum.
Does sound travel faster in air a liquid pure oxygen or in vacuum?
Due to the fact that sound does not travel in a vacuum, I would say that it is definitely not in a vacuum. But between oxygen and a liquid comes down to how sound is propagated. Sound is propagated by particles transferring energy by collision (which is why it cannot travel through a vacuum, no particles). Therefore, more particles you have in a given volume, the more likely collisions will happen, thus propagating the wave faster. Thus, sound would travel faster in a liquid due to its higher density.
What does light travel faster in?
It travels fastest in a vacuum.
Does light travel faster in glass then it does in a vacuum?
No, slower.
Sounds move faster in these media?
The media that sound moves faster in order are solids, then liquids, and then gases or air. Sound cannot travel in a vacuum because it is a vibration of molecules.
