Earth Optics Video 7: Biaxial Flash Figure

In this video, I go through examples of biaxial flash figures and introduce principal axes alpha, beta, and gamma. Examples show how to characterize along alpha and gamma.

Such a wonderful series of videos, thank you!

Do we have to know the optic sign of the mineral before we determine the fast and slow ray?

Great series but some of the pronouncinations hard to figure out.

Thanks for watching! Although I try to speak slowly and clearly, it's still a challenge to narrate these videos after growing up with a pretty heavy Staten Island accent. :D You can always turn on the closed captioning (CC) to help with parts of the video where the narration is unclear. Happy flash figuring!
