In general, light propagates at c, the speed of light (that is, 299,792,458m/s), however when travelling through a medium such as an optical fibre, this will decrease, but will still travel at a constant speed dependent upon values such as the materials permittivity and permeability. Light travels easiest through insulating mediums, and cannot travel far through conductors.
What else can I help you with?
Where will be speed of light minimum-water or air or vacuum or glass?
The speed of light is minimum in Glass. It is because light travels at minimum speed in solids.
The colour of light which travels through glass with the minimum speed is?
The color of light that travels through glass with the minimum speed is violet. This is because the speed of light in any medium, including glass, is dependent on the medium's refractive index, with shorter wavelengths like violet experiencing a slower speed.
When speed of the light will be minimum?
Speed of light is a constant factor. It is approximately 188,000 miles per second.
When is the only time that light travels at the speed of light?
Light always travels at the speed of light, although that's a different number in different substances.
Why is it important to explain the speed of light together with the medium in which the light travels?
The speed of light is dependent on the medium it travels through. Light travels fastest in a vacuum than in water or air.
How do you use light speed in a sentence?
A asteroid travels at the speed of light.
What is the mass of the body which travels in the speed of light?
The only thing that travels at the speed of light, is light. Light is also said to have no mass, therefore the only way for something to travel at the speed of light is for it to have no mass.
In what medium the speed of light will be minimum?
The speed of light is a set speed at which all electromagnetic waves travel at in a vacuum. It is 3*10^8 meters/second... That being said, when light, or any other EM wave, travels through a medium it will slow down. Every material has an index of refraction which is the ratio of the speed at which light travels in a vacuum, to the the speed it travels in that material. If you know the index of refraction, you can use Snell's law to determine the speed light will travel through a specific medium. Every medium is different, however a rule of thumb is the denser the medium, the slower light will travel through it. For example, light travels faster in the atmoshpere than it does in water.
The sound travels at the speed of light to your ear?
No, not quite. The sound travels at the speed of sound to your ear.
What makes light travel?
It only travels in the speed of light
Is electricity as fast as light?
No, electricity does not travel at the speed of light. The speed at which electricity travels depends on the medium it is passing through. In most cases, electricity travels at a fraction of the speed of light.
How does light travel witch is faster light or sound?
Light is much faster then the speed of sound. Sound travels at a speed of about 768 Miles per hour, when light travels at a speed of 186,282 miles per SECOND.
