Line 311: The reflectivity {{math\|''R''{{sub\|0}}}} between two media can thus be expressed both by the wave impedances and the refractive indices as <math display="block">\begin{align} R_0 &= \left\| \frac{~~n_2~~n_1 - ~~n_1~~n_2}{n_1 + n_2} \right\|^2 \\ &= \left\| \frac{Z_2 - Z_1}{Z_2 + Z_1} \right\|^2\,. \end{align}</math>
