Relativistic velocity addition describes the velocities of an object moving at a relativistic speed: u = v + u ′ 1 + vu. ′. c2. An observer of electromagnetic radiation sees relativistic Doppler effects if the source of the radiation is moving relative to the observer.

WebMay 9, 2024 · where ω = 2πf is angular frequency, z is position, and β is the phase propagation constant. At any given time, the distance between points of constant phase is one wavelength λ. Therefore, the phase velocity vp is vp = λf Since β = 2π / λ, this may also be written as follows: vp = ω β When light travels from a medium with a higher refractive index to one with a lower refractive index, Snell's law seems to require in some cases (whenever the angle of incidence is large enough) that the sine of the angle of refraction be greater than one. This of course is impossible, and the light in such cases is … See more Snell's law (also known as Snell–Descartes law and ibn-Sahl law and the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or … See more Ptolemy, in Alexandria, Egypt, had found a relationship regarding refraction angles, but it was inaccurate for angles that were not small. Ptolemy was confident he had found an accurate … See more Snell's law can be derived in various ways. Derivation from Fermat's principle Snell's law can be derived from Fermat's principle, which states that the light travels the path which takes … See more In a conducting medium, permittivity and index of refraction are complex-valued. Consequently, so are the angle of refraction and the wave-vector. This implies that, while … See more Snell's law is used to determine the direction of light rays through refractive media with varying indices of refraction. The indices of … See more In many wave-propagation media, wave velocity changes with frequency or wavelength of the waves; this is true of light propagation in most transparent substances other than a vacuum. These media are called dispersive. The result is that the angles … See more • List of refractive indices • The refractive index vs wavelength of light – Empirical relationship between refractive index and wavelength See more
