若原点处是简谐振动 f(t) = A sin(\omega t) , 则波函数 y(x,t)=f(t-\frac{x}{v}) = Asin(\omega(t -\frac{x}{v})) = A sin(\omega t - kx) , k = \frac{w}{v} 。 从波函数出发我们就可以推导出波动方 …
Direction of Wave: Asin(kx+wt) & Asin(kx-wt) - Physics Forums
2010年4月12日 · In case of Asin (wt+kx), the crest moves according to wt+kx=pi/2, that is x=pi/ (2k)-w/k*t, in the negative direction. Why does Asin (kx)sin (wt) represent a standing wave? Is …
Traveling Wave Equation $\sin (kx-wt)$ vs $\sin (wt-kx)$
2017年8月15日 · Using $\sin (kx-\omega t)$ or $\sin (\omega t-kx)$ does not make a difference: it is just a matter of convention. You can very legitimately change $A\sin (kx-\omega t)$ to $ …
