等厚干涉

条纹间距 $l=\frac{\lambda}{2n \sin \theta}$
光程差 $\delta =2nd=(2k+1)\frac{\lambda}{2}$

$b\sin \theta = N\frac{\lambda}{2}$

奇数明，偶数暗

$\frac{yd}{D}=k\lambda$

$\delta =r_1-r_2$

$k=m\omega ^2$

$u=\frac{\lambda}{T}$

$y=Acos \omega (t\mp \frac{x}{u})$

$\oint_{L}{\vec B d\vec l}=\mu _0\sum _i I_内$

$\vec B=\int_{L}^{}\frac{Id\vec l\times \vec r}{4\pi r^3}$

$\Phi _e=\oint_{S}\vec E d\vec s=\frac {\sum _i q_{i内}}{\varepsilon _0}$

$a_\tau =\frac{dv}{dt}=ar$

$a_n=\frac{v^2}{r}=r\omega ^2$
