WebA non-dispersive medium is that medium in which phase velocity and group velocity of a wave are same. Mathematically. v_p=w/k (here w is omega) v_g=dw/dk =v_p-lambda … In optics and in wave propagation in general, dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency; sometimes the term chromatic dispersion is used for specificity to optics in particular. A medium having this common property may be termed a dispersive medium (plural dispersive … See more The most familiar example of dispersion is probably a rainbow, in which dispersion causes the spatial separation of a white light into components of different wavelengths (different colors). However, dispersion also has … See more Material dispersion can be a desirable or undesirable effect in optical applications. The dispersion of light by glass prisms is used to construct See more The result of GVD, whether negative or positive, is ultimately temporal spreading of the pulse. This makes dispersion management … See more Waveguides are highly dispersive due to their geometry (rather than just to their material composition). Optical fibers are a sort of waveguide for optical frequencies (light) widely used … See more Most often, chromatic dispersion refers to bulk material dispersion, that is, the change in refractive index with optical frequency. However, in a waveguide there is also the … See more Beyond simply describing a change in the phase velocity over wavelength, a more serious consequence of dispersion in many applications is termed group-velocity dispersion (GVD). While phase velocity v is defined as v = c/n, this describes only one frequency … See more When a broad range of frequencies (a broad bandwidth) is present in a single wavepacket, such as in an ultrashort pulse or a chirped pulse or other forms of spread spectrum transmission, … See more

WebJul 9, 2024 · A medium in which speed of a wave is independent of frequency of wave is called a non-dispersive medium. For example, air is a non-dispersive medium for sound waves. What is the meaning of dispersive? 1 : of or relating to dispersion a dispersive medium the dispersive power of a lens. 2 : tending to disperse.

The dispersed phase is known as the internal phase, whereas the dispersion medium is called the external phase. Examples of the dispersed phase include dust in the air, whereas that of dispersion medium includes water in milk. them6 hieu ung hinmh anh vao side proshow
