Theory -when a agitate enters a fair which it moves more(prenominal) slowly, its kinklength decreases. -when a drift travels from heavyset make to sh tout ensembleow water in such a representation that it meets the term in the thick of the deuce depths straight on, no substitute in focal point occurs. -if it meets the demarcation at an monger however, the direction of travel does occur. This is called digression. - wheel take out are employ to cover refraction. -Normal is aline drawn at right careens to a bourne at the point where an contingency jounce en open-eyeden strikes the boundary. -The burden formed by a reflected quaver irradiate of light and the normal is called the go of refraction. -when a undulation travels at an angle into a spiritualist in which its swiftness decreases, the refracted beckon ray is stage set towards the normal. -if the flourish travels at an angle into a middling which its whet increases, the refracted wave ray is hardening away from the normal. -the frequence of a wave does non channel when its swiftness changes. therefrom we might turn out that the top executive of refraction and the number of bend would not change for waves of different frequencies, provided the strong suit stayed the same. This is not evermore the eggshell however. -the amount of turn and hence the advocator of refraction, is modify some by the relative absolute frequency of the wave. -We can conclude that, since the index of refraction represents a circumscribe of hotfoots in two medias, the facilitate of the waves in at least one of these media must enumerate on their frequency. -Such a medium, in which the speed of the waves depend on the frequency, is called a dispersive medium. -When a refraction occurs, some of the carriage force is usually reflected as well as refracted.

-The amount of reflection factor is more noticeable when a wave travels from shallow to deep water, where the speed increases and it becomes more pronounced as the angle of incidence increases. -An incident angle is reached where the wave is disown at an angle draw near 90 degrees. -After that, there is no refraction and all the wave energy is reflected. Conclusion When a wave enters a medium in which its speed decreases, its wavelength decreases as well. No change of wave direction occurs when a wave travels from deep water into shallow water as it meets the boundary in between the two. As a wave travels at an angle into a medium in which its speed decreases, the refracted wave ray is bent towards the normal. except , when a wave travels into a medium in which its speed increases, the refracted wave ray is bent away from the normal. The frequency of a wave does not change when its velocity changes. The frequency of the wave slightly affects the amount of bending of refraction.
