Mathematical Proceedings of the Cambridge Philosophical Society. 1969. Abstract The validity of Huygens' principle in the sense of Hadamard's ‘minor premise’ is investigated for scalar wave equations on curved space-time. A new necessary condition for its validity in….

WebHuygen's principle states that every point on a wavefront behaves as a source for secondary waves, whose common tangent (envelop) becomes the new wavefront. Using … WebThe Huygens-Fresnel Principle. 🔗. Fresnel made use of highly successful model of wave propagation put forth by Christiaan Huygens in 1690. This model is called Huygens' principle. Huygen imagined that each point of a wavefront serves as a source of new waves, which he called secondary wavelets. These wavelets have the same frequency … old town victoria museum

Web不确定性原理（Uncertainty principle）是海森堡于1927年提出的物理学原理。 其指出： 不可能同时精确确定一个基本粒子的位置和动量。 [8] 粒子位置的不确定性和动量不确定性的乘积必然大于等于 普朗克常数 （Planck constant）除以4 π [9] （公式：ΔxΔp≥h/4π）。 这表明微观世界的粒子行为与宏观物质很 ... 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’ principle is not correct in optics. It is replaced by Kirchoff’s [sic] modification which requires that both the amplitude and its derivative must be known on the adjacent surface… Many books and references e.g. and refer to the Generalized Huygens' Principle as the one referred by Feynman in this publication.
