WebbHuygens, a highly gifted theoretical and experimental scientist, is best known for his work on the theories of centrifugal force, the wave theory of light, and the pendulum clock. At an early age, Huygens began work in … 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. For waves propagating in a unidimensional medium, …

WebbWater wavefronts ( Source) In Huygens’ theory, there are primarily three kinds of wavefronts: spherical, plane, and cylindrical. Spherical wavefronts are produced by point sources. Plane wavefronts are produced by far-away sources and are in fact approximations of the spherical wavefront.

Webb波前（英文名：wavefront），有时也被称为波面。其实个人会觉得叫波面更贴切，因为它描述的就是一个和光线传输方向垂直的一个曲面，也就是光束中各等相位点所形成的面，与光束各点的传播方向垂直。举几个最容易理解的例子，如果是理想平行光，那么他的波前就是一个平面；换成一个点光源的话，对应的波前就变成一个球面（类似于电场线和等势 …
