Slightly less than 186,000 miles per second, or 300,000 kilometres per second. Light doesn't really slow much in air or gas, it is slowed by glass.

How fast is the speed of Light in a gas?

The only general answer that's true in all cases is: Slower than in vacuum. The exact speed depends on which gas, and the density of the gas, which in turn depends on its temperature and pressure.


What gases affect the speed of light?

In a vacuum, no gases affect the speed of light. However, when light passes through different mediums like air or water, the presence of gases can cause light to slow down slightly due to interactions with the gas molecules. This is known as the phenomenon of refraction.


Light incident upon a pane of glass shows down in passing through the glass. Does it emerge at a slower speed or at its initial speed?

The speed of light depends on the electrical characteristics of whatever medium it happens to be in at that instant. It has one speed in vacuum, another speed in air, another in glass, another in water, and yet another speed in jello. When passing from a more-optically-dense medium to one where its speed is higher, it doesn't need a stomp on the gas to 'accelerate' to the higher speed.


Does the pressure of a gas affect the speed of sound?

The speed of sound in a gas does not depend on pressure.See related links.There are limits to the validity of this statement because it is valid for gasses that behave as "ideal" gasses. Thus, when near a pressure and temperature that is close to the point that the gas will condense into a liquid, this statement fails. For air, at all the temperatures which we experience, the speed of sound in air is independent of pressure.


How fast is air molecules if temperature of the gas is 0 Celsius degrees?

The air molecules would go very slow because the air molecules are tight close together.

What happens to the speed of light when air changes to gas?

I'm afraid nothing happens to the speed of light ever. Also "air" is consider'd a gas.


What happens when light passes from air into gas?

When light passes from air into a gas, its speed and direction may change depending on the properties of the gas. This change in speed and direction is known as refraction. Additionally, some of the light may be reflected back at the boundary between the air and gas, causing part of the light to bounce off.

What path is light wave from air to gas?

Air is a gas.


At what velcity does light travel trought a gas?

It varies, depending on the gas, and on the properties of the gas (mainly temperature and pressure). But under "normal" circumstances, the speed of light in a gas is almost the same as the speed of light in a vacuum.


Does gas effect the speed of light?

Yes it does


is the rainbow gas?

its heat water and light and air no gas


How fast does light travel in a gas and why?

The speed will depend on the type of gas and on its density.

How fast does light travel in a gas?

The speed is relative to the gas and its density. It depends what kind of gas you're talking about. At 0 °C and 1 ATM pressure: Light travels at 299704644.53915 metres per second through air. Light has been slowed to down to 38 mph when passed through chilled sodium gas. Light has even been stopped to a halt.
