Ratio of the speed of light in a vacuum to the speed of light in a material?
The index of refraction.
The speed of light in a vacuum is 1.5 times that of the speed of light in a given material what is the index of refraction for that material?
Also 1.5. That's how the index of refraction is defined.
Formula for refractive index in terms of speed of light in vacuum and speed of light in a medium?
Refractive Index= Speed of Light in Vaccum / Speed of Light in the material
When the angle of incidence is greater than the critical angle all light within the material is?
hte light is reflected
What is the index of refraction for a material in which light travels with a speed that is 80 percent the speed of light in a vacuum?
It's 1/0.8 = 1.25
Why does light travel faster in empty spaces?
Light travels faster (up to the speed of light) in a vacuum, which is empty space. Light travels slower through a medium (matter).
What is the refractive index?
refractive index is the measure of how how fast or slow light travel through a material reference to the speed of light in empty space.
What does the Refractive index of a material signify?
The refractive index of a material signifies how much light slows down when it enters that material compared to its speed in a vacuum. It is a measure of how much the material can bend or refract light rays. Different materials have different refractive indices, which can impact how light interacts with them, such as causing light to be bent when passing through a lens.
What is the velocity of light in space compared to that in a denser medium?
The speed of light and all other electromagnetic wavelengths in vacuum (empty space) is higher than in any other medium.
Does light travel fastest through solids liquids gases or empty spaces?
Technically the speed of light does not vary because of the material, because the speed of light is a constant at around 300,000km/s
What is the speed of electricity or lightning compared to the speed of sound and light?
The speed of lightning is somewhere between that of light and sound which is why most scientists would agree that the speed of light and the speed of sound make a good comparison to that of lightning and electricity.
Compared to yellow light orange light has?
Compared to yellow light orange light has a longer wavelength.
Is light a translucent material?
Light is not a material. Material things have mass and light has no mass.
What is hypertect?
This is a type of high tech ultra light weight aluminum piston material for use in automotive engines. It has desirable strength and weight characteristics in comparison to cast pistons but lacks strength in comparison to Forged materials in piston manufacture.
Is aluminum light or heavy?
Compared to Osmium it is light, compared to Hydrogen it is heavy
Does light travel faster underwater than in air?
As compared to what? Compared to air, or to a vacuum, light travels quite a bit slower in water.As compared to what?

What is the property of a material that indicates how much it reduces the speed of light?
I think the property referred to on the question is the refractive index. Refractive index (n) is defined as the ratio of the speed of light in a vacuum (c) to the speed of light in the given material (v).n = c/vSo for glass, with a refractive index of 1.5, the speed of light in the material would be 200,000,000 m/s compared to speed of light in a vacuum of 300,000,000 m/s.
