Light travels fastest in pure vacuum, at the speed of light of 299 792 458 m/s (670,616,629 mph).
If there are any particles, some light will reflect off of those particles and bounce around, reducing its speed. With combinations of certain gasses, it is possible to slow light down to extremely low relative speeds. Scientists have even managed to stop a beam of light for a fraction of a second.
Light moves fastest in a vacuum (like space). All wavelengths of light (including visible, ultra violet, infra red, x-rays, etc) move at the same speed, 3.0*10^8 m/s in vacuum.

What else can I help you with?
Where do light waves travel fastest?
Light waves travel fastest in a vacuum, such as outer space, where there is no medium to slow them down. In most other materials, such as air or glass, light travels at a slower speed due to interactions with the atoms in the material.
In which state of matter will light travel the fastest explain?
Light will travel fastest in a vacuum, which is a state where there are no particles to slow down its speed. In other states of matter like solids, liquids, and gases, the particles can interact with light and slow it down as it travels through the medium.
Which travels fastest through a medium a photon atom sound or electron?
A photon travels fastest through a medium, followed by sound, then electrons. Photons travel at the speed of light in a vacuum, which is faster than the speed of sound or electrons in a medium. Sound travels at a much slower speed than light, while electrons generally move at speeds that are significantly slower than both photons and sound waves.
Through which medium does light travel fastest air glass or water?
Light travels fastest through air, then glass, and slowest through water. The speed at which light travels through a medium depends on the refractive index of the material, with lower refractive indexes resulting in faster speeds.
Where do light waves travel at their fastest?
Light waves travel at their fastest in a vacuum, where they travel at the speed of light, which is approximately 299,792 kilometers per second.
What color water does light travel through fastest?
According to the light spectrum, water should travel through a more violet coloured water the fastest. The speed of light through a medium is not governed by its wavelength, so colour is not a factor.
Where do light waves travel fastest?

Sound travels at a much slower speed than light, while electrons generally move at speeds that are significantly slower than both photons and sound waves.
Through which medium does light travel fastest air glass or water?
Light travels fastest through air, then glass, and slowest through water. The speed at which light travels through a medium depends on the refractive index of the material, with lower refractive indexes resulting in faster speeds.
Does light waves travel fastest through empty space?
Light waves, like all electromagnetic waves, travel without a medium, so they can travel through empty space. Sound waves, on the other hand, do require a medium to travel or propagate; therefore, they can not travel through empty space.
In what medium does sound travel fastest - solid -liquid - or gas?
Sound waves travel fastest through solids. *Generally, sound waves travel faster as the density of the transmission medium increases.
Where do light waves travel at their fastest?
Light waves travel at their fastest in a vacuum, where they travel at the speed of light, which is approximately 299,792 kilometers per second.
What EM radiations travel the fastest from its source?
All electromagnetic radiation in a given medium (water, air, vacuum, etc) travels at the same speed, the speed of light in that medium.
Which color of light travels fastest through a telescope lens?
All colors of light travel at the same speed in a vacuum, including through a telescope lens. The speed of light is determined by the medium it travels through; in air or a lens, all colors of light travel at the same speed.
What type of medium does light travels fastest?
A vacuum.
Can light waves travel fastest in air than water?
Yes, light waves travel faster in air than in water. This is because the speed of light is slower in a denser medium like water compared to a less dense medium like air. The speed of light in a vacuum is approximately 300,000 kilometers per second.
