Exercises for 5.3 Biaxial and Uniaxial Crystals P5.4 (a) Show that for a biaxial crystal, the directions of the optic axes are given by (5.25) in the x-z plane. (b) Show that (5.25) only makes sense if the axes are chosen such that ny is in between Nx and nz. Does the formula work if nx 2 ny 2 nz? How do the values of 0 relate to the case when n2 2 ny 2 nx? HINT: Use spherical coordinates as in (5.24). The two indices are the same when B2 – 4AC = 0. Under the assumption that пу lies between Nx and nz, B2 - 4AC = 0 can only be satisfied when 0 = 0.
