An example of refraction is a bending of the sun's rays as they enter raindrops, forming a rainbow.

Hi...
Refraction is the change in direction of wave propagation due to a change in its transmission medium.
The phenomenon is explained by the conservation of energy and the conservation of momentum. Owing to the change of medium, the phase velocity of the wave is changed but its frequency remains constant. This is most commonly observed when a wave passes from one medium to another at any angle other than 0° from the normal. Refraction of light is the most commonly observed phenomenon, but any type of wave can refract when it interacts with a medium, for example when sound waves pass from one medium into another or when water waves move into water of a different depth.
In optics, refraction is a phenomenon that often occurs when waves travel from a medium with a given refractive index to a medium with another at an oblique angle. At the boundary between the media, the wave's phase velocity is altered, usually causing a change in direction. Its wavelength increases or decreases, but its frequency remains constant.[citation needed] For example, a light ray will refract as it enters and leaves glass, as there is a change in refractive index. A ray traveling along the normal (perpendicular to the boundary) will suffer change in speed, but not direction. Refraction still occurs in this case (by Snell's Law as angle of incidence will be 0°). Understanding of this concept led to the invention of lenses and the refracting telescope.
Hope it helps you. :-)
