Optical Mineralogy Part 3 | Petrological Microscope & Propagation of Light | PPL & XPL IIT JAM GATE

Welcome to Optical Mineralogy Part – 3 by SP Geology 🌍 In this lecture, we discuss the structure and working of the Petrological (Polarizing) Microscope and understand how light propagates through different components of the microscope. This topic is extremely important for thin section study and competitive exams like IIT-JAM and GATE. 📚 Topics Covered: ✔ Introduction to Petrological Microscope ✔ Parts of Polarizing Microscope (Mechanical & Optical Parts) ✔ Lower Polarizer & Upper Analyzer ✔ Stage, Objectives, Eyepiece & Bertrand Lens ✔ Propagation of Light through Microscope ✔ Path of Light in Plane Polarized Light (PPL) ✔ Path of Light in Cross Polarized Light (XPL) ✔ Importance in Mineral Identification Understanding light propagation inside the microscope helps in interpreting optical properties such as birefringence, extinction, and interference colors. 🎯 Important for: IIT-JAM Geology GATE Geology CSIR-NET Earth Science BSc & MSc Geology Exams This lecture builds the foundation for advanced topics like interference figures and optic sign determination. 👉 Watch the complete Optical Mineralogy playlist in order for better understanding. 👉 Like, Share & Subscribe to SP Geology for more Geology lectures.
