When light travels through a given substance, the enegry of the light wave is constantly being absorbed and reemitted by molecules within the medium.
Therefore, when light travels through a vacuum (no molecules), it will travel at approximately 3X10^8 m/s, and when light travels through air, it will be slightly slower, due to the reduction in speed due to molecular absorbiton and resorbtion. (2.997X10^8 m/s). When light travels through dense matter, such as glass, it will slow more significantly.
This slowing or speeding up of light as it travels from one medium to the next is the primary cause of refraction. This is rather hard to conceptualize through text, but this is the best way that I can describe it. Picture a wave of light as a maching band in file. On concrete, they walk at a given speed. On mud, they walk at a lesser speed. Say the (light) band is approaching the concrete/mud barrier at an angle. When the front corner of the bank hits the mud, it will slow while the other corner of the front remains the same speed. Since one corner is traveling more slowly, the front of the band/light will "pivot" until the entire front of the wave is in the second medium, causing a change in the direction of the light. Kind of muddy, eh?
This process occurs from during transition between medias.
Therefore, for example, when you look at the surface of water, the light you see is actually bent (refracted) from a point where it physically isn't.
What else can I help you with?
How does refraction work in water?
When light passes from air into water, its speed decreases, causing it to bend or change direction. This bending is known as refraction, and it occurs because light travels at different speeds in different materials. The amount of refraction depends on the difference in the refractive indices of the two materials.
What is it called when a wave goes from one medium to another and it changes speed and direction?
It is called refraction. Refraction occurs when a wave changes speed and direction as it travels from one medium to another, due to the change in its wave velocity and the change in the medium's optical density.
Are sunglasses reflection or refraction?
Sunglasses primarily work through absorption and polarizing light to reduce glare. They do involve some refraction when light passes through the lenses, but this is not the main mechanism by which sunglasses reduce glare.
How does the angle of refraction change as the index of refraction of the bottom material increases?
As the index of refraction of the bottom material increases, the angle of refraction will decrease. This relationship is governed by Snell's Law, which states that the angle of refraction is inversely proportional to the index of refraction. Therefore, higher index of refraction causes light to bend less when entering a denser medium.
How do you think increasing a medium's index of refraction might affect the angle of refraction?
Increasing the medium's index of refraction will cause the angle of refraction to decrease. This is because light bends more towards the normal as it enters a medium with a higher index of refraction.

Refraction.

Do you need total internal refraction to get the fiber optics to work?
Not internal refraction - internal reflection. And yes, that's essential to make fiber optics work.

What is refraction in photography?
In Photography, refraction has the same rules as in physics. Well, photography is all about engineering and physics. Refraction encompasses the situation where light goes through a semi transparent object and the photons are slightly drifted from its normal course because the surface they hit separates them. You can see this effect inside a pool or when you look at your own reflection at a cracked mirror.
