$ \gamma^2 \gg \Delta n_r$の極限で、空気中での臨界角が幾らになるか求めよ。

2-7解答

$\displaystyle \theta$ $\displaystyle \sim \sqrt{ 2\Delta n_r} =\left(2\cdot 0.0003\right)^{1/2} \left(...
...}\right)^{1/2} =0.025 \left(\frac{\Delta n_r}{0.0003}\right)^{1/2}\,[{\rm rad}]$    
  $\displaystyle = 1.4 \left(\frac{\Delta n_r}{0.0003}\right)^{1/2}\,[{\rm deg}]$ (57)
