Well light can be seporated through glass but all light moves at the same pace it wont make a difference. Like the sun its rays move the same.
Actually you're wrong. light travels fastest in a vacuum
So light travels faster in air than in glass. The speed of light in vacuum is nearly 300,000 km per second, which is incredible but that is true.
Short Answer:
Light travels at about 75% its speed in water as it does in air. In air, it is amost the same speed as in a vaccum.
Long Answer:
The speed of light in air is very nearly the same as its maximum speed in vacuum. In water, the speed of light is three fourths its value in a vacuum.
Specifically, the relationship between the speed of light in a material, v, and the speed of light in vacuum, c, is the index of refraction, n.
Precisely, n=c/v or in the form we need it, v=c/n.
The index of refraction for the vacuum 1.00000, for air at STP, 1.00029 and for waterat 20 C. 1.33.
Speed of light in vacuum, v=c.
Speed of light in air, v=c/1.00029.
Speed of light in water, v=c/1.33.
Density, temperature impact light's speed Does temperature effect the speed of light? Ask your own question! This is a very interesting question! Some things, like chocolate syrup, flow much faster when they are warm compared to when they are cold. But light is not like that, its speed is independent of temperature. There is, however, an indirect way temperature can affect how fast light travels through a material, but before we discuss that, let's look at some basic facts. The speed of light plays a very special role in physics. In 1861 James Clerk Maxwell first recognized the connection between electric induction and magnetic induction, and showed that the speed of light was determined by two well known constants of nature. Then in 1905, Albert Einstein dramatically raised the significance of the speed of light through his theory of relativity where he postulated that nothing in the universe could travel faster than the speed of light. He labeled the speed of light as c, and said that it was a constant of the universe. Furthermore, he stated that mass and energy are equivalent through the relation E=mc2. So the speed of light, c, is a very important number in our world. For this to be a good standard, it has to work everywhere and under all conditions. A meter in Ithaca, NY has to be identical to a meter in Istanbul, Turkey, or to a meter on the surface of the sun, or on the frozen planet Neptune. This can only be true if the speed of light is the same in all these places, and if it is not affected by external effects like temperature. So the value of c is independent of temperature. What about that indirect impact of temperature on the speed of light that was mentioned at the beginning of this article? You might have noticed that the speed of light, c, is defined only for a perfect vacuum. If light travels through something that has mass, such as air or glass, the velocity is reduced. The velocity of light in these materials is given as c/n, where n is called the refractive index of the material. A perfect vacuum has an index of refraction equal to unity, but almost all other materials have an index greater than one. Window glass has a refractive index of approximately n=1.5, so light travels with a velocity of about 2/3 c in glass. Air has an index of 1.0003, so the speed of light in air is nearly the same as in vacuum, but just a little slower. As a rule of thumb, materials which have higher density have larger refractive indices. If the density of a material changes with temperature, the speed of light in that material will also change. Have you ever seen "heat waves" coming off an object that is hot? This is due to hot air rising and bending the light rays that travel past the object. Hot air has a lower density than cold air, so light travels faster in hot air than in cold air. As the hot air mixes with the surrounding cold air, the light goes slightly faster in the hot regions, and this causes the distortion. So, the speed of light can be indirectly affected by temperature, but only if the medium the light is traveling through changes density.
Light travels faster in dense air because the hotter the air the faster the light travels in the air
Yes, it is true.
True.
cooler air.
I would think in warmer Air....
cooler
The room becomes cooler because warmer air goes out, and cooler air comes in.
We can say that air we breathe out is warmer, because if we breathe out on a mirror we can see droplets of water which means air is hotter compared to normal room temperature air because the room air condenses. Exhaled air is warmer than inhaled air because its the same room temperature air which we have taken in.
Convection. The hotter air is less dense than the cooler air already there so, the warmer air will rise to the top of the house while pushing the cooler air down.

faster
the air molecules are moving faster
Because there is more warmer air that will rise, and cooler air will move in to take its place, creating wind.
The land heats up faster than the ocean. The air over the ocean is cooler and denser. The air over the shore is warmer and less dense. The cooler air moves to the warmer air an pushes the warmer air upwards. Cool flowing air is wind.
when there is more moisture in the air, it is warmer and thicker. when there is less moisture in the air it is cooler and thinner. so if it is cooler temperature then it will drop faster.
Because that how air rules.
Speed of sound is proportional to absolute temperature. It should therefore travel faster in warmer weather.

cooler
Cooler air is lighter and rises to the top, while warmer air is heavier and sinks to the bottom. There is actually a cycle of heating and cooling of the air, which causes wind. Te longer the cooler air is of higher altitude, the warmer it is going to get; this is also true of the warmer air, but vise versa. The warmer air gets cooler and starts to rise while the cooler air gets warmer and starts to sink.
If I Am Not Mistaken Cooler And Cooler.
