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.
Assuming you mean "Why":Water has an index of refraction close to 4/3, while air has an index of refraction close to 1. As a result, light changes its direction when changing over from water to air. It is this which causes the distortion.
A deep-water wave.
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.
15 minutes to half an hour.
I would cut the TIME of each one in half. it has the same effect.
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.
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.
Yes gargoyles do have nipples because they are half man, half a distorted creatures and need them.
no because it it is to dence for the water which it will make it appear wider but it will not spread out
Mermaids don't have wands. they are not fairy creatures that need wands. They can control water, water objects or animals with hand movements or thinking about it. unless it is a half fairy half mermaid, mermaids DON' T have wands,

It is currently unknown if Kandi will appear in any more episodes of Two and a Half Men.
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.
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.
cause they are broken in half..
half of a clock
The letters DS do not appear on a Half-Sovereign.
