The speed of light is the speed at which electromagnetic waves propagate through a medium. The speed of sound is the speed at which acoustic waves propagate through a medium. As the speed of sound relies on the medium moreso than the speed of light, sound propagates much slower than light.

What is the ratio of the speed of light in a vacuum to the speed of light in a different medium?
This is called the index of refraction. When light crosses the boundary between mediums (media) with different indices, it is bent (refracted).It's usually defined the other way around ... the ratio of the speed of light in vacuum to its speed in the medium. Since the speed of light is greater in vacuum than in any medium, the number is always greater than 1. It's referred to as the "refractive index" of the medium.
How is the refractive index of one medium with respect to the otherrelated to the speed of light?
The refractive index of any substance is(speed of light in vacuum)/(speed of light in that substance) .The number is greater than ' 1 ' in any material medium.
Which is a comparison of the speed of light in a material compared to the speed of light in empty space?
The speed of light in any material medium is less than it is in empty space.
In a vacuum the speed of ultraviolet radiation is faster than the speed of light?
no
Why is the speed of light limited in a vacuum?
The speed of light is not limited in a vacuum - the speed of light is fastest in a vacuum. But that is what Einstein called the "Cosmic Speed Limit" - nothing can move faster than the speed of light in a vacuum, or even quite asfast.
Is the speed of sound as speed of light?
The speed of light is much greater than the speed of sound.
Is wavelength of sound greater than light?
no,wave length of sound is equal to wavelength of sound as when thunder appears,light appears first than sound because of more speed than sound but we can't considere that wave length of sound is greater than that of light
Jan saw the flash before she heard the sound what does this tell you about the speed of light and the speed of sound?
It tells you that the speed of light is greater than the speed of sound.in the environment that Jan was in
The speed of sound in a solid is what than the speed of sound in air?
greater
Is the speed of light or sound faster?
The speed of light is about 880 thousand timesfaster than the speed of sound.
What is farster the speed of light or the speed of sound?
The speed of light is more than 850 thousand times the speed of sound.
Is the speed in water vapor greater than speed in water?
Not the speed of sound.
Is the speed of sound in steel greater than speed in water?
Yes.
What accounts for the time difference in seeing and hearing an explosion?
The difference in the speed of sound and the speed of light. Light travels much faster than sound, so you will see it, and then hear it. The further away, the greater the time difference.
Is there a tiny particle that can faster than the speed of light and sound?
no, not that i know of though but im sure nothing is faster than the speed of light and the speed of sound is slower than the light
Why the speed of electron beam is greater than the light speed in cathode ray oscilloscope?
Why is the speed of the electron beam greater than the speed of light in cathode ray oscilloscope.
Why you see a distant event before you hear it?
Because the speed of light is much faster than the speed of sound. Therefore, when the light from that event reaches your eyes, you see it. Then later, the sound from the event reaches your ears, and you hear it. Basically it's just because light travels faster than sound.
