How long would it take for the speed of light to travel a quintillon miles?
The speed of light doesn't travel anywhere. However, light itself, traveling through vacuum at the speed of light, covers 1 quintillion miles in about 170,108 years. That's less than 7 percent of the distance to the nearest galaxy. (Note: The American definition of 'quintillion' is used . . . 1 x 1018 . Using the British definition of the same word (1030), the answer is the same, only 1 trillion times bigger.)
When the mineral uvarovite has an index of refraction of 1.86. calculate the speed of light in this sample of uvarovite.?
Use the definition of "index of refraction". In this case, you simply need to divide the speed of light in a vacuum by the index of refraction.
What is the definition of average speed called?
It is called a definition.
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.
What is the definition of speed of light?
The definition of the speed of light in a vacuum is 300,000,000 meters/sec, or 186,000 miles/sec.
Why is the speed of light medium?
The speed of light is not medium: in vacuum, it is the highest speed that there can be. Hardly a definition of medium!
What is the speed it takes your light bulb to transmit at the speed of light?
By definition, light travels at the speed of light. About 300,000 kps
What is the speed of light in light years per second?
The number of years in a second... by definition!
Is definition of speed of light can be said to be example of circular logic?
In Wikipedia speed of light is defined as 'in international distance of units (SI) the meter is defined as the distance of light traveled in vac-cum in 1/299,792,458 of the second. This definition fixes the speed of light at 'exactly' 299,792,456 meters/second. This definition is the 'classic' example of what is called as 'circular logic'. When it comes to shape of kidney, you say that it is bean shaped. When it comes to shape of bean, you say, it is kidney shaped. Here you take the help of meter to define the speed of light and when it comes to length of meter, you take the help of speed of light.
What is superluminal travel?
Travel faster than the speed of light. By definition, Superluminal is "Faster-than-light (FTL)"
What is the definition of speed in physics?
Velocity (speed) is distance traveled per unit time, e.g. speed of light is 186,300 miles per second
What is the definition for EMC2?
e for energy, m for matter, c for speed of light and 2 for square.
IS electromagnetic waves travel faster than speed of light?
Electromagnetic waves are, by definition, light. So they travel at the exact same speed as light.Also, a "Do" would be appropriate here, instead of an "IS".
What is light's acceleration if its traveling at a constant speed of 300000 km s?
It has no acceleration. The definition of acceleration is the change in velocity over time, so if it is traveling at a constant speed, it has no acceleration. Also, the speed of light is a constant, which means it does not change.
What is the meter definded by?
The current definition of the meter is in terms of the speed of light: "... the distance travelled by light in free space in 1⁄299,792,458 of a second".
When the mineral uvarovite has an index of refraction of 1.86. calculate the speed of light in this sample of uvarovite?
Use the definition of "index of refraction". In this case, you simply need to divide the speed of light in a vacuum by the index of refraction.
