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.
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.
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
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. (It doesn't vary depending on altitude, or any other factor.)
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.
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.
Is the speed of sound equal to the speed of light?
No, not even close. Light travels at 300,000,000 meters/sec but sound only at 340 meters/sec
What causes light rays to refract?
light travels in straight path and when speed of medium in which light travels change then it refract due to change in speed light rays bend and refract
Does light travel fastest through solids liquids gases or empty spaces?
Technically the speed of light does not vary because of the material, because the speed of light is a constant at around 300,000km/s
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
What color travels most slowly in glass?
The speed of light does not vary by the color that it is perceived as, so all of the colors should travel at the same speed.
How fast did chariot go?
They travel to the speed of light? to it? and where exactly is the speed of light?
What causes light rays to bend when they enter a new medium in a new angle?
when light rays enter a new medium in a new angle it may speed up or speed down
