Is it possible to make prism deviation angle minimum (as a function of incidence angle) more abrupt?

Dear Sirs, The setup for the dispersion measurement is as follows. Hg lamp, collimator, goniometer with triangular prism. We measure the light dispersion using the prism. To do so we determine...

1. If I can quantize the atom using this hyperbolic spiral and classical physics, could nature do the same?

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...
