What else can I help you with?
If light cannot travel faster than it does in a vacuum no index of refraction can ever be less than zero?
True ---Apex.
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.
Does sound travel faster in a vacuum?
No, sound cannot travel in a vacuum because it requires a medium, such as air, water, or a solid material, to propagate. In the absence of a medium, there are no molecules for the sound waves to travel through, so they cannot propagate and cannot travel.
What is the one thing that cannot travel through a vacuum?
i think voice cannot travel through vacuum.
Which wave would travel fastest in a vacuum light or sound?
Light would travel faster in a vacuum compared to sound. Light travels at the speed of light in a vacuum, which is approximately 300,000 kilometers per second, while sound cannot travel in a vacuum as it requires a medium to propagate through, such as air, water, or solids.
Suppose light travels 1.5 times faster in a vacuum than it does in glass. What is the index of refraction for glass Express your answer as a decimal.?
The index of refraction for glass is calculated by taking the speed of light in a vacuum and dividing it by the speed of light in glass. Since light travels 1.5 times faster in a vacuum, the index of refraction for glass would be 1 divided by 1.5, which equals 0.67.
Does light travel faster in a vacuum?
Yes.
Do electromagnetic waves travel at the same speed as a vacuum?
They travel faster
Sound cannot travel in?
A 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.
Is vacuum the sound that travels best?
No: worst. Sound cannot travel though a vacuum.
Does light travel faster in a material with a higher index of refraction?
No, light travels slower in a material with a higher index of refraction compared to vacuum or air. This is because the speed of light is inversely proportional to the index of refraction of the material according to the equation v = c/n, where v is the speed of light in the material, c is the speed of light in vacuum, and n is the index of refraction.
