Theory of wavefronts in 1600
WebbReflection, refraction and diffraction are all boundary behaviors of waves associated with the bending of the path of a wave. The bending of the path is an observable behavior when the medium is a two- or three-dimensional medium. Reflection occurs when there is a bouncing off of a barrier. Reflection of waves off straight barriers follows the ... WebbWho came up with the theory of light? In his Traité de la Lumière (1690; “Treatise on Light”), the Dutch mathematician-astronomer Christiaan Huygens formulated the first detailed …

WebbSpherical waves are generally seen as sound waves and light waves. They have a point source and the waves formed, move forward in all directions. A plane wave moves forward in only one direction. A true plane wave ceases to exist in reality. This is because then it would require filling the entire space, which is not seen in experiments. WebbIn 1657 the French mathematician Pierre de Fermat presented an intriguing derivation of Snell’s law based on his principle of least time, which asserted that light follows the path …
WebbDiffraction is a phenomenon by which wavefronts of propagating waves bend in the neighborhood of obstacles. Diffraction around apertures is described approximately by a mathematical formalism called scalar diffraction theory. Diffraction problems are among the difficult encountered in optics, and exact rigorous solutions are quite rare. The first …
In physics, the wavefront of a time-varying wave field is the set (locus) of all points having the same phase. The term is generally meaningful only for fields that, at each point, vary sinusoidally in time with a single temporal frequency (otherwise the phase is not well defined). Wavefronts usually move with time.
