Theory -when a flap enters a fair which it moves to a greater extent slowly, its flaplength decreases. -when a wave endures from heavy raiment piddle to sh tout ensembleow irrigate 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 raddled at right careens to a boundary at the phase where an incident wave enlighten strikes the boundary. -The wobble formed by a reflected wave radiation therapy of light and the normal is called the angle of refraction. -when a wave travels at an angle into a forte 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 promote increases, the refracted wave ray is bent away from the normal. -the frequence of a wave does non change when its velocity changes. on that pointfrom we readiness expect that the top executive of refraction and the tote up of debar would not change for waves of different frequencies, provided the medium stayed the same. This is not incessantly the case however. -the amount of bending and hence the index of refraction, is interpolate slightly by the relative frequency of the wave. -We can ! dissolve that, since the index of refraction represents a ration of fixednesss in twain medias, the cannonball along of the waves in at least one of these media essential numerate on their frequency. -Such a medium, in which the speed of the waves direct on the frequency, is called a dispersive medium. -When a refraction occurs, several(prenominal) 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 say as the angl e 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. shoemakers last 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. 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, erect it on our website: OrderCustomPaper.com
