Based on what we know, we can confirm that the wave behavior being observed when light passes through media of different densities is refraction.
<h3>What is refraction?</h3>
This is a term used to explain the behavior of light as it moves through distinct mediums. This behavior includes a change in direction of the light due to its change in speed.
Therefore, the wave behavior being observed when light passes through media of different densities is refraction.

<span> When a gas is cooled, it contracts. In a sealed environment, the pressure would therefore reduce, as the molecules try to get closer together, that is, push outwards less. But in the atmosphere, the closer-packed molecules (or atoms, of course) make the air more dense, therefore heavier.
If you were at a higher elevation, the cooling is caused by the reduced pressure causing the molecules to move further apart. The temperature reduces about 1 degree Centigrade for every 100metres gain in elevation.
Any good? </span>
