Cont'd from "Left Side, Right Side, Bounded And Kinky" dated 10 Aug 2015,
For the case of \(\mu_2\gt\mu_1\),
\(\alpha_{2s}\lt\alpha+\Delta\theta\)
and
\(\alpha_{2p}\gt\alpha-\Delta\theta\)
It is possible that \(\alpha_{2s}\) crosses below \(\alpha_{2p}\) when \(\Delta\theta\lt0\). \(\alpha_{2s}\) is not necessarily the left beam. \(\Delta\theta\) can be adjusted to swing the beams over \(\alpha\).
