Calcite [CaC03] is a crystal with abnormallyr large birefringence. The index of refraction for light with electric field parallel to the optical axis {called extraordinary waves or e-waves} is 1.4864. The index of refraction for light with electric field perpendicular to the optical axis (called ordinary waves or 0- waves) is 1.6584. Find the critical angle {producing total internal reflection) for e-wuves in calcite leaving the block of calcite into air. Express your answer in degrees to four significa nt Figures
