2016年10月24日 · I know that the particles within a loop are in phase (Phase difference -0°)with each other and antiphase (180°) with the particles in the next loop. Then what about the phase …

2019年3月14日 · Looking at graphs of this like I mention in the comments it's always helpful. You can also look at the math. It's easier to work with complex exponentials and then take the …

2017年5月6日 · If it is induced by a smaller than proportional amount than that in the secondary coil, that is the eddy current; why is it in phase with the current in the primary coil while that …

$\begingroup$ Antireflection coatings(ARC) on solar cells work by facilitating destructive interference between partially reflected waves from the air-ARC interface and ARC-solar cell …

2018年8月24日 · What does it mean that all points between two adjacent nodes in a standing wave oscillate in phase? I sort of get what in phase means, it means that the peaks and …

2017年6月3日 · Points are in phase if $\Delta\Phi$ is a multiple of $2\pi$, and they are in antiphase if $\Delta\Phi$ is a multiple of $2\pi$ plus $\pi$. $\endgroup$ – John Rennie …

Actually, one wave and its 180 flip phase image can be seen as two waves with the same phase but with opposite amplitude (when one is positive the other is negative).
