What is a vacuum in scientific way?
Something that has no air. Like the vacuum you have in your closet. It sucks air in because it is trying to fill the empty cavity that it has inside is. Space is a vacuum because their is no air in Space. If you take your helmet off in Space you will die instantly because you have air and the vacuum around you is MUCH MORE POWERFUL!
Light travel fastest in?
a vacuum (space is pretty much a vacuum). It slows down when it goes through gas, even more through water, glass or diamond (causing refraction or bending of the light).
What is vacuum of space?
Vacuum we mean that there is nothing in the space. But perfect vacuum is not possible even in space as there are some traces of hydrogen molecules. More over space itself is having some properties such as magnetic permeability and electric permittivity. So space is considered as a medium through which light could travel. But sound cannot travel as it needs material medium. Hence sound waves are called as mechanical waves where as light waves are named as electromagnetic waves.
Does light travel faster through space or through window?
Light travels faster through space than through a window. In a vacuum, such as space, light moves at its maximum speed of approximately 299,792 kilometers per second (186,282 miles per second). When light passes through a window, it slows down due to interactions with the glass, which has a higher refractive index than a vacuum. This causes the light to travel more slowly in the glass compared to its speed in space.
Does light travel fastest in space in air in water or through glass?
Light travels fastest in a vacuum, such as in space. It slows down when passing through different mediums like air, water, and glass due to interactions with atoms and molecules in those materials, which cause the light to refract and bend.
What transperent objects can slow the speed of light?
Anything that is transparent i.e. allows light to pass through, can slow the speed of light. The speed of light C is measured in a vacuum at 2.98 x 108 ms-1, if light is able to pass through any object that is not a vacuum e.g. water, this value will be less as the medium is more dense than a vacuum. Light is made up of particles called Photons, which will collide with the particles that make up any medium, slowing them down. Therefore, the only medium in which light can travel at it's maximum speed is in a vacuum, as by definition a vacuum is empty space and there will be no collisions.
In a vacuum there is no what?
In a vacuum there is no matter. A vacuum is the absence of mass in a given volume of space, so an evacuated space has nothing material in it. There may be electromagnetic energy of some kind or another, however.About the most perfect vacuum we know of is in intergalactic space. In that space, which is the space between galaxies, there is very little matter. Perhaps only a few atoms (and probably of hydrogen) in a given cubic meter is about all that we think is out there. But light and microwave background radiation will be present. In a partial vacuum, which is all that we are able to create, there would be a number of atoms of stuff there owing to the imperfections of our equipment.

What does a vacuum in space contain?
Vacuum we mean that there is nothing in the space. But perfect vacuum is not possible even in space as there are some traces of hydrogen molecules.

But sound cannot travel as it needs material medium. Hence sound waves are called as mechanical waves where as light waves are named as electromagnetic waves.
What is the speed of light at zero degrees centigrade?
The speed of light in a vacuum is 300,000 kilometers/second. The concept of "temperature" isn't very relevant in empty space (or in nearly-empty space).When considering the speed of light in anything else than a vacuum (for example, in air, glass, or water), the material through which it travels is much more relevant than the exact temperature.
Why light travel in vacuum but not sound?
Light requires nothing more than a source for transmission. sound requires a source and a medium to conduct it. In vacuum, there is no conductor for sound.
Can you make a vacuum in outer space?
No problem ! Outer space is already a vacuum ... full of it ! I used to read that space is a better vacuum than any vacuum that can be produced in a laboratory on earth. Maybe that's not true any more. Bu the fact remains: Space is a pretty good vacuum. Open a pickle jar in outer space, wait 30 seconds, shake it around a couple times, then screw the cover back on, tight. When you get back, you'll have a jar full of the best vacuum any of your friends have ever seen. (Hard to prove, though.)
Is fire in space blue?
Fire in space can appear blue because the lack of atmosphere means there are no particles to scatter the light. This allows the higher-energy blue light to be more visible. However, the color of the fire can vary depending on the composition of the fuel and the temperature at which it burns.
