Reflection is a change of the angle of light without a change of medium. Refraction is a change of the angle of light with a change of medium.

When light enters another medium it changes speed, but thewavelength changes correspondingly so that the frequency does not change. For example, if light enters a medium where its speed is cut in half, then the wavelength will also be reduced by half.
It is the extent of the change in the direction of light as it passes from one transparent medium to another.
When light waves are passed from one medium to another, they are . . . refracted. (Bent)
As light rays pass from one medium into another, they bend (or "refract"). This can be easily seen by trying to poke at something under water from above the surface (for example, aim a drinking straw at a target in a glass of water). This refraction is a consequence of the change in direction due to the wave-qualities of light, as the speed of the light is affected by the change of medium.
