That's a reasonable question, and a very important one. Unfortunately, I can't
give you an exact answer, because it depends on the temperature, pressure
and humidity of the air, and also somewhat on the wavelength of the light.
Giving all of those variables some 'average' value, the refractive index of air
is 1.00027, meaning that the speed of light with that wavelength in that air
is 1/1.00027 of its speed in vacuum, or
299,711,536 meters (186,232 miles) per second(reduced from [ 299,792,458 meters / 186,282 miles ] per second in vacuum).
What else can I help you with?
How much faster is the speed of light compared to earth speed?
The speed of light is not always fixed at 299792458 m/s. In earth's atmosphere, the speed of light slows, though this is negligible. In water, light travels at 75% of c, and in a diamond, light travels at .40 c. C is the speed of light, rounded to 300,000 km/s.
What makes light waves change speed as they travel from the sun to the Earth's surface?
Light has a single speed in a vacuum - which is almost 300,000 kilometers per second. Once light enters Earth's atmosphere, it will be slightly slower.
What name is applied to light that is bent in the atmosphere?
The name applied to light that is bent in the atmosphere is "refraction." This bending of light occurs due to the change in speed as light travels through different mediums with varying densities, such as air through the Earth's atmosphere.
What speed does all light travel at?
In space and in earth's atmosphere, the speed is the same, approximately 299, 792, 458 meters per second.
Why are helium and the free hydrogen very rare on earth?
Too light and too close to the 1/6 rule in escape speed from earth's gravity. A gas must be withing 1/6 of the escape speed from earth's escape speed for it's gravity to be easily retained in the earth's atmosphere. These two gases are heated too easily. are too light and too close to the escape speed to hang around unfixed, or untrapped in the atmosphere.
How many miles per hour does it take for light to travel from the sun to the earth?
In a vacuum, the speed of light is always 670,616,629 miles per hour (300,000 kilometers per second). The speed of light changes as it enters a different medium, such as Earth's atmosphere, but the change in speed is essentially negligible.
What is the speed of light from sun to the earth?
The sun is roughly 8 minutes and 19 seconds away from earth in light speed!!! Imagine how far away it is in normal earth speed!?!? The speed of light is about 186,000 miles per second.
What color of light is scattered the most by the molecules in Earth's atmosphere?
Blue light is scattered the most by the molecules in Earth's atmosphere.
How fas does light travel?
Light in its fastest state in a vacuum only can travel at 3.0*10^8km/s but as it enters the earth's atmosphere, the atmosphere is full of dust particles and layers of gases which can effect the speed of light slightly, in the earths atmosphere light travels at 2.89*10^8 km/s .
When a meteoroid enters Earth's atmosphere it produces a streak of light called a?
The streak of light created by a meteoroid entering the Earth's atmosphere is called a meteor. A meteorite is the remains of a meteoroid that did not vaporize after entering the Earth's atmosphere.
What is a bright streak of light that comes from a meteoroid burning in eats atmosphere called?
A bright streak of light produced by a meteoroid burning up in the Earth's atmosphere is called a meteor. Commonly referred to as a "shooting star," this phenomenon occurs when the meteoroid enters the atmosphere at high speed, causing it to heat up and emit light as it vaporizes. If the meteoroid survives its passage through the atmosphere and reaches the Earth's surface, it is then called a meteorite.
What displays of light is caused by something burning up in earth's atmosphere?
When something burns up in Earth's atmosphere, it creates a bright streak of light known as a meteor or shooting star. This is caused by the friction and heat generated as the object enters the atmosphere at high speed, causing it to glow and disintegrate. If the object survives and lands on Earth, it is known as a meteorite.
