Course Code: B23004H
Course Name: Modern Optics
Lecture Time: 30 sessions, 2 hours/session
Form a systematic and clear physical image from aspects of basic theory, basic concepts and basic analysis method,at the same time combine its link with modern optics. Master the basic theory, basic concepts, basic analysis methods and basic experimental skills of optics in the category of general physics. Four class hours of experimental teaching enables students to master the basic experimental skills, and consolidate the theoretical knowledge through experiments. Through this course, students will have a deeper understanding of three main subjects of optics: the nature of light, the propagation of light and the interaction between light and matter.
