Chain Source Scaling Three-Row Scan - Electromagnetic Waves and Polarization Step by Step

A fixed two-stage polarizer chain scales with source intensity. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

The same two-stage chain scales with source intensity

The first stage is aligned and the second stage is the same slanted polarizer in every row, so changing the source changes every stage.

\begin{array}{c}S_{\mathrm{a}}=25\\S_{\mathrm{b}}=25\\S_{\mathrm{c}}=25\left(\frac{3}{5}\right)^{2}=9\end{array}

The same two-stage chain scales with source intensity

The first stage is aligned and the second stage is the same slanted polarizer in every row, so changing the source changes every stage.

\begin{array}{c}S_{\mathrm{a}}=50\\S_{\mathrm{b}}=50\\S_{\mathrm{c}}=50\left(\frac{3}{5}\right)^{2}=18\end{array}

The same two-stage chain scales with source intensity

The first stage is aligned and the second stage is the same slanted polarizer in every row, so changing the source changes every stage.

\begin{array}{c}S_{\mathrm{a}}=75\\S_{\mathrm{b}}=75\\S_{\mathrm{c}}=75\left(\frac{3}{5}\right)^{2}=27\end{array}
