The particle that is light is called the Photon. The photon is massless and can travel faster than any other particle because it has no mass. Any particle that has mass will require infinite energy to reach the velocity of light, which is impossible because the particle will have infinite mass in the process (Remember E=mc^2).

∙ 11y agoAccording to the Special Theory of Relativity, this isn't possible.
One of the reasons is that it would require an infinite energy to speed up an object to the speed of light - and it would acquire an infinite mass.

X-rays travel in vacuum at a higher speed than the visible light?
No. Both travel at exactly the same speed. The speed of light.
How does light travle in a material with a higher index of refraction?
It will usually change. Usually you would expect the speed to decrease, but note that the "optical density", i.e. the index of refraction, is not entirely related to the density (as defined by mass/volume).
Where is the speed of light greater than the speed of light in water?
The speed of light through vacuum is constant. The speed of light through air is slightly less. The speed of light through water or some other medium is even less than that. The factor by which the speed of light (and its wavelength) is reduced within a medium is called the "index of refraction" (which determines the amount of bending that occurs when light goes from one medium to another).
How do different materials affect light and sound waves?
Light slows as it enters material with a higher density whereas sound waves speed up in materials of higher density. Light bends towards the "normal" as it passes from a less dense medium to a higher density medium ie air into glass. Both sound and light can be reflected from surfaces.
Light incident upon a pane of glass shows down in passing through the glass. Does it emerge at a slower speed or at its initial speed?
The speed of light depends on the electrical characteristics of whatever medium it happens to be in at that instant. It has one speed in vacuum, another speed in air, another in glass, another in water, and yet another speed in jello. When passing from a more-optically-dense medium to one where its speed is higher, it doesn't need a stomp on the gas to 'accelerate' to the higher speed.
What is speed of light in more refractive index?
Higher the refractive index, less the speed of light
What is the speed of light travel by aeroplane?
There hasn't been up to time of answer an aircraft fly at or higher that the speed of light
X-rays travel in vacuum at a higher speed than the visible light?
No. Both travel at exactly the same speed. The speed of light.
An object moves in light speed will shred its mass?
An object that normally doesn't move at light speed (so, this doesn't include photons for example) CANNOT move at the speed of light. As it approaches the speed of light, its mass will get higher and higher (and tend towards infinity); as will the energy required to continue speeding it up.
Which has higher refractive index?
The one in which the speed of light is less has.
How does light travle in a material with a higher index of refraction?
It will usually change. Usually you would expect the speed to decrease, but note that the "optical density", i.e. the index of refraction, is not entirely related to the density (as defined by mass/volume).
What are some properties of light?
It travel in a higher speed than sound
When do light waves change speed?
speed of light is different for materials of different refractive index and also higher the refractive index lesser will be speed of light in that medium. so if light travels from rarer to denser medium (with respect to refractive index) then light waves will change their speed
What are some useful properties of light?
It travel in a higher speed than sound
The speed of light in air compares with the speed of light in glass because?
The speed of light in air is much faster than in glass. This is because the density of glass is much higher than that of air so it slows the lightwave down much more.
What happens to the light ray when it passes from a low speed medium to a higher speed medium?
It changes direction, according to Snell's Law.
Where is the speed of light greater than the speed of light in water?
The speed of light through vacuum is constant. The speed of light through air is slightly less. The speed of light through water or some other medium is even less than that. The factor by which the speed of light (and its wavelength) is reduced within a medium is called the "index of refraction" (which determines the amount of bending that occurs when light goes from one medium to another).
