Refraction facts. Refraction is the change in direction of a wave, caused by the change in the wave's speed. Examples of waves include sound waves and light waves. Refraction is seen most often when a wave passes from one transparent medium to another transparent medium. Different types of medium include air and water.

The greater the change in speed, the more the light is refracted ( bent ).The bigger the angle of incidence. The more the light is refracted unless the light enters the new substance at 90oin which case it will slow down but not change direction.Converging lenses are sometimes called convex lenses. This type of lens converges parallel rays of light to a point. Converging lenses bulge outwards in the middle.
Diverging lenses cause parallel rays of light to spread out. This type of lens is often called a concave lens.

Each colour refracts at a different angle (...
This phenomenon is known as refraction. The medium from where the light is incident is called the incident medium, and the medium where refraction occurs is called a refractive medium. Refraction is caused by the change in direction and speed of light. This happens because light travels at different speeds in different mediums.

Refraction happens when light changes direction, or bends, when it moves from one material to another. For example, light traveling through the air refracts when it hits water. This can make a straw in a glass of water look bent at the surface of the water. Some surfaces neither reflect nor refract light. They absorb, or take in, light.

What is the difference between reflection and refraction?
How is refraction seen?
The amount, or degree, of refraction is related to the difference between the speeds of light in the two materials of different densities—the greater the difference in densities, the more the speed changes, and the greater the bend.
