Vaccum is basically emptiness. There is nothing in vaccum. Light can travel faster in vaccum than in any other medium because there is no obstruction for the passage of light. It is the rarest medium.

Light travels faster in a vacuum compared to air. In a vacuum, light travels at its maximum speed of about 186,282 miles per second. When light travels through air, its speed is slightly slower due to interactions with air particles.

∙ 15y agoit travels so fast that you cant see it!! it travels VERY FAST!
A Better answer The speed of light in free space is a physical constant defined as 299,792,458 metres per second. But for ease of use it's generally 186,000 miles per second, or 300,000 kilometers per second.

Does light in air travel faster than radiation from microwave oven?
No, both light in air and radiation from a microwave oven travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second. Therefore, they both travel at the same speed.
Light travels faster in?
Light travels faster in a vacuum than in any other medium, such as air or water. Its speed in a vacuum is approximately 186,282 miles per second (299,792 kilometers per second).
How does the speed of sound vary in air water solids and a vacuum?
In a vacuum, sound doesn't exist at all, because it needs some sort of medium through which to travel. (Light, however, can travel in a vacuum.) In air, at 20 °C (68 °F), sound travels at 343 meters per second. The speed increases with temperature and varies if different gasses are used. Sound travels much faster in liquids than in air (or any gas). In water, it is about 4.3 times faster than air at 20 °C. In solids, the speed of sound depends greatly on the type of solid, though is generally faster than in air. In lead, for example, it travels at 1960 m/s, but goes 5640 m/s through glass.
What is quicker speed of sound or speed of light and why?
The speed of light is faster than the speed of sound. The speed of light in a vacuum is approximately 186,282 miles per second, while the speed of sound in air at room temperature is around 767 miles per hour. Light travels much faster because it does not require a medium to propagate, unlike sound waves which need a medium (such as air, water, or solids) to travel through.
Does sound travel faster in air a liquid pure oxygen or in vacuum?
Due to the fact that sound does not travel in a vacuum, I would say that it is definitely not in a vacuum. But between oxygen and a liquid comes down to how sound is propagated. Sound is propagated by particles transferring energy by collision (which is why it cannot travel through a vacuum, no particles). Therefore, more particles you have in a given volume, the more likely collisions will happen, thus propagating the wave faster. Thus, sound would travel faster in a liquid due to its higher density.
What materials can light travel through faster than it travels through air?
Light can travel faster through a vacuum than through air. In a vacuum, light travels at its maximum speed of about 299,792 kilometers per second. This is because there are no particles in a vacuum to slow down the light's speed.
What does light travel faster through?
Light travels faster through a vacuum than through any other medium, such as air, water, or glass. In a vacuum, light can travel at its maximum speed of approximately 299,792 kilometers per second.
Can the speed of sound travel faster than the speed of light?
No. Light in vacuum is roughly 880 thousand timesas fast as sound in air.
Do sound waves or light waves travel faster?
Light waves travel faster than sound waves. The speed of light in a vacuum is about 186,282 miles per second, whereas the speed of sound in air is about 767 miles per hour.
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.
Does light in air travel faster than radiation from microwave oven?
No, both light in air and radiation from a microwave oven travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second. Therefore, they both travel at the same speed.
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 light travel faster through air water vacuum or glass?
Light travels fastest in a vacuum because there are no particles to slow it down. It slows down in air, even more in water, and even more in glass due to interactions with particles in those mediums.
Is vacuum a medium of light?
No, a vacuum is the absence of any medium, including air. Light can travel through a vacuum because it does not require a medium to propagate.
Does light travel faster underwater than in air?

Does most wave travel at the same speed?
No, different types of waves travel at different speeds depending on the medium they are traveling through. For example, light waves travel faster in a vacuum than in other materials. Sound waves travel faster in solids than in gases.
Can air travel faster than light?
No.
