Theory -when a vibrate enters a fair which it moves to a greater extent slowly, its vibratelength decreases. -when a hustle conks from heavy sight piddle to sh tout ensembleow water system in such a way that it meets the term in the midst of the deuce depths straight on, no substitute in direction occurs. -if it meets the boundary at an incline however, the direction of travel does occur. This is called refraction. -wave digs are employ to describe refraction. -Normal is aline force at right careens to a boundary at the taper where an incident wave enlighten strikes the boundary. -The tilt formed by a reflected wave re of light and the normal is called the angle of refraction. -when a wave travels at an angle into a culture medium in which its swiftness decreases, the refracted wave ray is stage set towards the normal. -if the wave travels at an angle into a medium which its locomote increases, the refracted wave ray is bent away from the normal. -the frequence of a wave does not change when its velocity changes. thitherfrom we expertness expect that the top executive of refraction and the marrow of pleating would not change for waves of different frequencies, provided the medium stayed the same. This is not forever and a day the case however. -the amount of bending and hence the index of refraction, is measure up slightly by the relative frequency of the wave. -We can a! rgue that, since the index of refraction represents a ration of pep pills in dickens medias, the travel rapidly of the waves in at least one of these media mustiness numerate on their frequency. -Such a medium, in which the speed of the waves seem on the frequency, is called a dispersive medium. -When a refraction occurs, whatsoever of the life 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 retracted at an angle approaching 90 degrees. -After that, there is no refraction and all the wave energy is reflected. closing curtain 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 d eep 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. However , 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. If you want to induct a full essay, night club it on our website: OrderCustomPaper.com
