Spherical wave physics Britannica
The Huygens–Fresnel principle (named after Dutch physicist Christiaan Huygens and French physicist Augustin-Jean Fresnel) states that every point on a wavefront is itself the source of spherical wavelets, and the secondary wavelets emanating from different points mutually interfere. The sum of these spherical … See more In 1678, Huygens proposed that every point reached by a luminous disturbance becomes a source of a spherical wave; the sum of these secondary waves determines the form of the wave at any subsequent time. He assumed … See more Many books and references e.g. and refer to the Generalized Huygens' Principle as the one referred by Feynman in this publication. Feynman defines the generalized principle in the following way: "Actually Huygens’ … See more • Fraunhofer diffraction • Kirchhoff's diffraction formula • Green's function See more Consider the case of a point source located at a point P0, vibrating at a frequency f.

WebJun 12, 1995 · Wavelets are a powerful tool for planar image processing. The resulting algorithms are straightforward, fast, and efficient. With the recently developed spherical … WebThe seismic wavelet is the link between seismic data (traces), interpretations and the geology (reflection coefficients). It must be accurately known (estimated or measured) … WebFor a sinusoidal spherical wave, the wavefronts are spherical surfaces that expand with it. If the speed of propagation is different at different points of a wavefront, the shape and/or orientation of the wavefronts may change by refraction. In particular, lenses can change the shape of optical wavefronts from planar to spherical, or vice versa. qng-info
