SUMMARY
The discussion centers on the phenomenon of birefringence, specifically addressing the confusion surrounding the depiction of refraction at an angle of incidence of 0°. Users reference Snell's law, which states that the angle of refraction should also be 0° under normal incidence. However, it is established that in birefringent materials, the extraordinary ray propagates at an angle, leading to apparent discrepancies in visual representations. Key resources include Wikipedia and Physics Bootcamp for further clarification on double refraction.
