Why does a straw bends when you put it in a glass of water?
The light gets refracted in water. Thus the shape of the straw seems to be bent.
If you put a straw into a glass of water the straw looks to be bent although nothing has physically happened to the straw?
That is not strictly correct. The straw has undergone physical change: it is wet!
Why does a straw appear broken as it sits in a glass of water?
Refraction bends the light, making the straw appear to be broken.
A straw placed in a clear glass of water appears to break at the waters surface. Which explains this effect?
Refraction... The change in the density of the medium (from water to air) - causes the straw to appear to be bent.
Does light bend as it passes through materials?
Light is affected by the media that it travels through. Even air will bend light. Glass and water certainly bend light.
Why does a straw appear to be bent in a glass of water?
This is due to the principle of refraction. Refraction occurs at the boundary of the two media air and water. When a light ray hits this boundary at an angle, it changes direction and seems to bend. So. the straw appear bent when we look at it through the water glass because light is being bent as it passes through the different media of air, water, and the glass.

Do straw float in a glass of water?
Yes, plastic drinking straws will float in water.
What parts of the Chinese drilling process do the glass of water THE straw and the empty glass represent?
drilling

Why does a straw fall out of a glass of coke?
What happens when you put a straw in a glass of Coke or any other carbonated beverate, is that bubbles of carbon dioxide form on the straw and cling to it, and since these are lighter than water, they tend to lift the straw up out of the Coke; when it is lifted high enough it will become unballanced and fall out of the glass.
Does water absorb light?
It doesn't water refracts or bends the light which is why the straw looks bent in a glass of water
How does light bend without any source?
It bends in water or a magnifying glass.
Why is it very difficult to spear a fish unless you are under water?
Because when light passes from water into are - it refracts or bends. This makes the fish appear to be in a different place to where it actually is. You can demonstrate the effect using a glass of water and a drinking straw. Half-fill a glass with water, then lower one end of a straw into it. You will see the straw 'bends' as it hits the water. It's the same effect in spearing fish.
Capillary is the smallest kind of blood vessel?
In the body, capillary tubes are in fact microscopic. However, the capillary effect can be viewed on a much larger scale. If one was to place a straw in a glass of water, one would see that the water level in the straw is higher than that of the glass of water, this is because the molecules of water are attracted to the wall of the straw, and each other.
