What might cause the speed of light to vary?
The speed of light varies depending on what kind of material it's traveling through. It's fastest when in vacuum, and it's different, and slower, in air, water, alcohol, oil, glass, jello, etc.
Formula for refractive index in terms of speed of light in vacuum and speed of light in a medium?
Refractive Index= Speed of Light in Vaccum / Speed of Light in the material
Is speed that does not vary is called average speed?
No, speed can vary and one can still calculate the average speed of an entire trip. Average speed is equal to the change in distance divided by the change in time.
What travels at 300 000 km per second?
That is the speed of light.That is the speed of light.That is the speed of light.That is the speed of light.
Why is the speed of light limited in a vacuum?
The speed of light is not limited in a vacuum - the speed of light is fastest in a vacuum. But that is what Einstein called the "Cosmic Speed Limit" - nothing can move faster than the speed of light in a vacuum, or even quite asfast.
Does convection or conduction travel at the speed of light?
No. The speeds of convection and conduction vary, but they are nowhere near the speed of light.
What is the speed of light at sea level called?
The speed of light in a vacuum is called the speed of light, which is approximately 299,792,458 meters per second.
How fast does speed of light travel on venus?
Speed of light doesn't travel. Light travels.The speed of light doesn't vary depending on the planet; it may, however, vary depending what it goes through. For example, the speed of light in a vacuum is 300,000 km/second; the speed of light in glass is about 2/3 of that value.
What causes light to change directions?
The change in speed of light changes the direction.
What happens to the speed of light when it is refracted?
The speed of light decreases when it enters a denser medium and is refracted, such as water or glass. The change in speed causes the light to change direction at the boundary between the two media.
Where do the light waves coming from the pencil change speed?
The light waves coming from the pencil change speed when they move from air (faster speed) to the glass or water (slower speed). This change in speed causes the light waves to refract or bend.
Why does the speed of light vary?
The speed of light varies because the absolute speed of light "C" is measured in a vacuum. When light travels through air, it goes slightly slower. When light travels through denser mediums still, such as glass, the speed decreases further still.
Does light always travel at the same speed in all mediums?
No, light does not always travel at the same speed in all mediums. Its speed can vary depending on the medium it is passing through.
What causes the most bending in light?
When light passes from one medium to another with a different optical density, such as air to glass, it experiences the most bending at the interface due to a change in speed. This change in speed causes the light to refract or bend.
How does the speed of light of different colors passing through the same medium vary?
The speed of light of different colors passing through the same medium remains the same. This is because the speed of light in a medium is constant and does not change based on the color of the light.
What causes light to accelerate?
Light does not accelerate. In a vacuum, light always travels at a constant speed of approximately 299,792 kilometers per second, known as the speed of light. It only changes speed when it passes through different mediums.
Is light faster in cold or warm air?
basicly the answer is that light speed does not vary due to weather. This is a difficult subject to understand I really recommend the wikipedia light speed article. Go below for the link
