refraction -- light has a lower velocity in medium other than a vacuum, where light achieves the highest velocity (~3E8 m/s). In general, the denser the medium, the slower the speed. The actual relation is expressed as Snell's law, which relates the indices of refraction to the angles of entrance and exit relative to the normal. When light travels from one medium to a different medium, the path changes its direction right at the boundary (the angle of incidence is different from the angle of refraction), giving your eyes an illusion of the part of the object submerged in water being located a distance away from its actual location.
What else can I help you with?
A wave moving in water that is deeper than half its wavelength is called what?
A deep-water wave.
Is a bottle of water a pint?
Bottles come in many different sizes, the most common use the metric system of measurement, a typical bottle of water would be 500mls (half a litre) or larger.
How long does it take water to get hot in a gas hot water heater that has been shutoff for several months?
15 minutes to half an hour.
Would you cut the number of baths or showers you take in half if you knew it could improve the quality of water in your area?
I would cut the TIME of each one in half. it has the same effect.
How fast does half a stick of chalk dissolve in water?
In order to dissolve chalk in water, vinegar needs to be added. The vinegar has acid in it that eats away at the chalk to dissolve it.
How can refraction make objects look?
Refraction occurs when light changes speed as it moves from one medium to another, causing it to change direction. This change in direction can make objects appear distorted or bent when viewed through the refracting medium, such as a lens or water.
Do Gargoyles have nipples?
Yes gargoyles do have nipples because they are half man, half a distorted creatures and need them.
Do clay in a half full jar of water spread out?
no because it it is to dence for the water which it will make it appear wider but it will not spread out

I think the song you are referring to is "How Low Can You Go' in which Ludacris does half of the bridge in a distorted litlle kid voice.
What instrument measures objects?
One could use a caliper to measure relatively small objects. Also, a scale would measure its weight. If it is regularly shaped with some straight edges, use a ruler.. You can drop it in a measuring cup half full of water and measure how much water it displaces.
What do the letters DS represent on a gold or Half-Sovereign?
The letters DS do not appear on a Half-Sovereign.
What objects are shaped like acute angles?
half of a clock
When you put a pencil in a half filled glass of water why do it appear to be broken?
When light passes from air into water, it changes speed and direction due to the difference in density, causing the pencil to appear bent at the water's surface. This phenomenon is called refraction. Although the pencil isn't actually broken, the way light bends as it enters the water creates the illusion of a break due to the change in the medium.
When did JFK appear on the U.S. half dollar coin?
