The refractive index of air is 1.000293
The velocity of light in a medium is given by v = c/n, where n is the refractive index and c is the speed of light, 299792458 m/s
Therefore the velocity of light in air is (299792458 (m/s)/1.000293), or 299704644.5 m/s

∙ 11y agoThere's no limit to the distance that light can travel in air.
The light does suffer some absorption, and therefore some attenuation,
as it travels through air. So there will be a question of how far it can go
before you can no longer detect it. But that's a question of your capability,
not the capability of the light.

∙ 13y agoThe speed of light through air is almost the same as the speed of light through a vacuum. The speed of light roughly is 3 * 10^8. Thus also roughly the speed of light air being that.

Is one meter the distance traveled by a ray of light in vacuum?
One meter is the distance travelled by light in vacuum in 1/299 792 458 second.
What is the difference between ultraviolet and visible radiation?
ultraviolet radiation has a greater frequency than visible light, that is to say that it cycles ("travels up and down") more times per distance traveled. it can also be expressed as having a shorter wavelength (distance traveled during one cycle) than visible light
True or False - The speed of light is directly proportional to the distance traveled please explain why?
False. The speed of light is always the same: 300,000 kilometers per second.
Is the magnitude of displacement greater than or equal to the magnitude of the distance traveled?
Displacement can be equal to distance traveled or less, depending on the shape of the route, but it can never be greater than the distance traveled.
Can distance traveled by an object be negative?
NO
What is the distance traveled in a year at the speed of light?
It is known as a light year.
The distance traveled by light in a year?
It's Nova ;)
What is the distance in a year traveled at a speed of light known as?
It is known as a light year.
What is an explanation of a light year?
The distance traveled by light in a one year period :3
What is 5865696000000?
The Distance traveled in miles in 1 light year. TL
Distance traveled by light in 1 second?
In a second, light travels about 300,000 km., or 3x108 meters.
Is a light year 150 million km?
No. 150 million km is the distance from Earth to Sun, and this distance is called an AU (astronomical unit). Light travels this distance in about 8 minutes.A light-year is the distance traveled by light in a year, which of course is much more than the distance traveled in 8 minutes. A light-year is approximately 9.461 x 10 to the power 12 km.
What is the distance traveled by an object divided by the time in which the distance was traveled without identifying the direction traveled?
Speed describes the distance traveled by an object divided by the time in which the distance was traveled, if the direction is not specified.
Is one meter the distance traveled by a ray of light in vacuum?
One meter is the distance travelled by light in vacuum in 1/299 792 458 second.
What are distance traveled and time traveled and rate of travel related?
Rate of travel = (distance traveled) divided by (time traveled)
How far is the light-year?
A light year is the distance traveled by light in one year's time (in space). This equates to 5,878,499,810,000 miles or 9,460,528,400,000 kilometers.
What is the formula for distance traveled?
distance traveled = speed multiplied by time taken.
