Why speed of light is greater than speed of sound?

Anonymous

∙ 14y ago

Updated: 9/19/2023

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.

Not the speed of sound.

Which travels at a greater speed light waves or sound waves?

Light waves travel at a greater speed than sound waves in a vacuum, moving at approximately 186,000 miles per second. In comparison, sound waves travel much slower through air, at around 767 miles per hour.

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.
