Light Refraction
Sunlight gets refracted when it moves through a glass of water. Light of different wavelengths gets bent a different amount. This breaks the light into different colors. Sometimes, you can see the colors on your wall!
Did you ever wonder why a straw in a glass of water looks like it is bent? This is another example of refraction. Light slows down more when it passes through water than when it passes through air. This makes light waves change direction. To our eyes, the straw looks like it is bent.

Refraction can even make a straw in a glass of water look broken, as it does in this photo. It is making the part of the straw
in the water look wider, too.View Larger Image
