Reverse Vector Snell's Problem
Is there a simple way to reverse the Snell's-Equation-in-Vector-Form problem? I.e., given the incident and transmitted vectors $\,\mathbf{i}\,$ and $\,\mathbf{t}\,$ (both with norm = 1), find the ...

Snell's law in vector form
Snell's law of refraction at the interface between 2 isotropic media is given by the equation:
\begin{equation}
n_1 \,\text{sin} \,\theta_1 = n_2 \, \text{sin}\,\theta_2
\end{equation}
where $\theta_1$...
