GLY 4200 NAME HOMEWORK 9 Optical Indicatrix and Interference Colors Suppose a mineral has a retardation of 350 nm. What interference color would this produce? 1) orange - yellow (order & color) If this mineral is examined with a 1° red accessory plate and the fast directions of the plate and the mineral are parallel, what is the retardation? 2) 900 nm What color would this correspond to? 3) 2° orange - yellow If the fast directions are perpendicular, what will the retardation equal? 4) 200 nm What color would this correspond to? 5) 1° white Suppose a mineral has a retardation of 200 nm.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.
