No, depending on the matter, speed of light can vary. It's speed is inversely proportional to the viscosity of the matter. It travels the fastest through Vacuum>>Air>>Liquids>>Solids.

∙ 14y agoNo; a denser medium will slow the light down. When the speed of light is quoted, unless otherwise stated, it is implied that it's through a vacuum.
The primary example of this is the speed light travels through water or glass. The different speeds are what create the rainbow effect, essentially splitting the light by slowing down different wavelengths at a different rate.

∙ 8y agoNo, the speed of light depends on the material. The denser the material the slower light travels. The 'speed of light' normally quoted is the speed in a vacuum.

Is the speed of light is the same in every medium?
No; a denser medium will slow the light down. When the speed of light is quoted, unless otherwise stated, it is implied that it's through a vacuum. The primary example of this is the speed light travels through water or glass. The different speeds are what create the rainbow effect, essentially splitting the light by slowing down different wavelengths at a different rate.
Why is the speed of the different colors of light in air the same?
All wavelengths are the same physical phenomenon ... electromagnetic radiation ... whose speed depends on the electrical properties of the medium in which it is propagating. Why would you think that they should travel at different speeds ?
Is speed of light uniform or not?
The speed of light in a vacuum is constant everywhere. The speed of light in a particular medium depends on what the medium is. It moves slower in air than in a vacuum, and slower in water than in air.
Do electromagnetic waves travel through a meidum by the speed of light?
Electromagnetic waves will travel with the same speed that light travels in that medium. Be careful though, the speed of light in vacuum or air is 300000 Km/s. That doesn't mean that in any medium it would be this. It depends on the nature of the medium. In any case, the first statement ALWAYS holds.
What is the speed of light in oil?
Einstein says that the speed of light is the same to all observers. This raises some interesting problems and his theories of relativity set out to solve them. But that aside, the speed of light is the same in olive oil and a diamond as it is anywhere else.
Is speed of light in vacuum and medium same?
No, light in a medium will travel at a slower speed.
Which light has the ACCURATE speed?
ANY light traveling through the same medium (stuff) has the same speed.
Can all wavelengths of light travel at the same velocity in certain mediums?
Yes, all wavelengths of light have the same velocity in every medium. In fact, all types of electromagentic radiation travel at the same speed in a given medium.
Is the speed of light changed when it is reflected back into the same medium?
No.
Can the speed of light be changed?
no. speed of light is always constant . as long as the light stays in the same medium. the speed is generally slightly different in different media.
When light moves from one medium into another its speed?
Its speed changes but its frequency remains the same.
Is the speed of light is the same in every medium?
No; a denser medium will slow the light down. When the speed of light is quoted, unless otherwise stated, it is implied that it's through a vacuum. The primary example of this is the speed light travels through water or glass. The different speeds are what create the rainbow effect, essentially splitting the light by slowing down different wavelengths at a different rate.
Does light always travel at the same speed?
The speed of light is always the same as long as it's traveling through the same medium. But its speed is different in different media, and those are all less than its speed in vacuum.
Why is the speed of the different colors of light in air the same?
All wavelengths are the same physical phenomenon ... electromagnetic radiation ... whose speed depends on the electrical properties of the medium in which it is propagating. Why would you think that they should travel at different speeds ?
Is speed of light uniform or not?
The speed of light in a vacuum is constant everywhere. The speed of light in a particular medium depends on what the medium is. It moves slower in air than in a vacuum, and slower in water than in air.
Does the color of a laser affect the velocity?
Light always travels at the same speed, the speed of light. At least in vacuum. In a medium light will travel at a slower pace, and the speed decrease is dependent on the color (wavelength) of the light. This is because the refractive index (which determines how fast light can travel through a medium) is color dependent.
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.
