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.

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 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.
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
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 the straw in the water look broken?
Due to the phenomenon of refraction being caused; straw appears to be bent in water.
What is difraction?
when something looks bent when you put a straw in a cup of water and it looks bent that is difraction
What are common examples of light bending?
Rainbows, a straw looking bent in a glass of water, microscopes, telescopes, prisms, a stone looking closer to the surface of water than it actually is, and eyeglasses.
Why does a spoon appear bent when immersed in a half filled glass of water?
A pencil in water looks bent because of refraction. when light enters a substance with a different density than the one it came out of, the light either slows down or speeds up. this makes the light appear bent. If there is a pencil in the water, it appears bent because the light is traveling at different speeds through water and air.
What happens to the straw placed in plastic cup full of water?
straw seems at above from the bottom and seems to be broken because water bent the rays of light as the light leaves the water it is bent or refracted from its usual straight line.
If you are in water up to your waste and you look at your legs and feet and they look short and stubby and you're tall and thin what is happening?
Get a clear glass and half fill it with water. Place a straw or stick in the glass and if you look form the side you will see that where the stick enters the water it appear to have a kink in it. This is because the path of light is bent (refracted) by the water. When you stand in water and look down at your legs, this bending of the light make the image of your legs took foreshortened.
Does a pencil remain the same when it is dipped in a glass of water?
Physically, the pencil remains a straight pencil. Optically, due to the refraction effect of water, the pencil will appear to be bent.
Why does an oar appear to be bent when part of it is in the water?
Refraction.
