Evaporation In The Atmosphere

Do I worry? If the T-Rex was such a good predator, how come it was outlived by the chicken?

Evaporation causes cooling - Heat - Physics

When the droplets become large enough, they fall to the ground as rain. Evaporation commonly occurs in everyday life. When you get out of the shower, the water on your body evaporates as you dry. If you leave a glass of water out, the water level will slowly decrease as the water evaporates. One important example of evaporation is sweating. The sweat requires energy to evaporate off of your skin.

It gets that energy from the excess heat your body is producing, in turn causing you to cool down. Much like evaporation, condensation also occurs in day to day life. When you walk outside on a cold day, you can see your breath as you exhale. The air leaving your lungs is much warmer than the outside air temperature, causing the water vapors to condense into a small mist. Condensation is also seen when you take a hot shower and the bathroom mirror fogs or steams up. As the air heated up it came in contact with the cool mirror and condensation occurred on the surface. A prism is an example of refraction.

It also illustrates that the extent of refraction of light depends on the color.

In a prism, light is refracted as it enters and as it leaves the prism and the light waves of different colors change directions by different amounts so that when they exit the colors are seen at different angles. Rainbows have color because of refraction in a manner similar to a prism.

The rainbow results when light waves encounter drops of water. There is also reflection involved and a full explanation is more complicated than the case of a prism. All lenses including the lenses in eye glasses function because of refraction. Light enters the lens on one side and because the surface of the lens is curved, the angle of light inside is different depending on the place on the lens surface where it entered.

That is called focusing light. It happens again as the light exist the lens. The eye itself has a lens that operates because of refraction and creates the image on the retina of the eye. When you look into water, the objects that you see are not in the location where the image appears.

Native peoples who hunted fish with a spear learned that you do not through the spear at the image of the fish because the angle of the light changes coming out of the surface of the water and makes it appear as though the fish is slightly displaced. Sound refracts as does any other wave.

One can not easily notice this, but if you are under water and sound enters from the air, the apparent direction will shift by some angle. Water waves refract and it is easily demonstrated with a co-called ripple tank.

The 32 Most Important Examples of Evaporation

When the depth of water changes, so does the speed of a wave. In a ripple tank one can place a flat surface on the flat bottom of a tank so there are two different water depths separated by a straight edge. Waves creates in one depth that encounter the edge at an angle will be seen to change direction. This is most obvious for very shallow depths around a centimeter. Ocean waves change speed and so also demonstrate refraction but it is not clearly seen unless there is an edge such as described for the ripple tank. Ocean waves are a different sort of wave than a ripple but still can show diffraction.

One can obviously see the change in speed and wavelength of waves as they come to a shore and that is related to the refraction process.
