WebIn physics and electrical engineering the reflection coefficient is a parameter that describes how much of a wave is reflected by an impedance discontinuity in the transmission medium. It is equal to the ratio of the amplitude of the reflected wave to the incident wave, with each expressed as phasors.For example, it is used in optics to calculate the amount of light … WebRefraction and light bending. You might have heard people talk about Einstein’s speed of light, and that it’s always the same.

"Webteodoro. 10 years ago. Specular reflection is the mirror-like reflection of light (or of other kinds of wave) from a surface, in which light from a single incoming direction (a ray) is reflected into a single outgoing direction. Such behavior is described by the law of reflection, which states that the direction of incoming light (the incident ... " - Optics reflection

Optics reflection

WebNov 8, 2024 · What Is Reflection? When a wave reaches the interface between two different media, typically some of the wave will bounce back into the original medium. This process is known as reflection. A familiar example of reflection is optical reflection in mirrors, where light waves reflect off a smooth surface. In optics and electromagnetics in general, "reflection coefficient" can refer to either the amplitude reflection coefficient described here, or the reflectance, depending on context. Typically, the reflectance is represented by a capital R, while the amplitude reflection coefficient is represented by a lower-case r. These related concepts are covered by Fresnel equations in classical optics.

WebNo, if total internal reflection really occurs at every part i.e. if the angle of incidence is large enough, it should have nothing to do with refractive index or the nature of the cladding material. However, irregularities in the boundary between the core and the cladding fibre results in loss of intensity (attenuation). Comment. ( 4 votes) Flag.
