coherent wave 是相干波。那么应该是频率相等。in phase 指的是相位相同
The phase velocity (or phase speed) of a wave is the rate at which the phase of the wave propagates in space. This is the speed at which the phase of any one frequency component of the wave travels. For such a component, any given phase of the wave (for example, the crest) will ...
那对于这类题,其实就是不懂原理的学生毫无头绪、无从下笔,但是其实真正了解how wave travels的小伙伴们应该能马上就能明白,这类题我们只需要知道两个因素就可以轻松解答了。 1. 产出这两个波的Two sources在最一开始是in phase 还是 anti phase? 2. 这两个波距离P点的距离是否会因为path difference而产生phase...

By using a Hall-MHD model, we numerically studied the propagation of the Alfvén waves and the phase mixing in a one-dimensional inhomogeneous magnetized plasma in the present paper.The Alfvén waves, the phase mixing and the fast magnetosonic wave are excited by the boundary condition in inhomo...
Ever since its discovery1, the notion of the Berry phase has permeated all branches of physics and plays an important part in a variety of quantum phenomena2. However, so far all its realizations have been based on a continuous evolution of the quantum s
