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.
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.
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.
Ice water placed in a dry glass on a warm summer day will cause the water to appear on the outside of the glass.What is the process that forms water on the outside of the glass?
The process is called condensation, the ice water touching the glass causes the glass to cool and which causes the water vapour in the air to condense on the outside of the glass.
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 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.
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.

Do straw float in a glass of water?
Yes, plastic drinking straws will float in water.

What makes a fish appear larger when placed in spherical fish bowl?
fish in tanks are magnified by the glass and the water.......... in my round fish bowl my guppies look huge
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
