Polarization examines the directional nature of light vibrations and provides evidence for the transverse nature of light. Students study Brewster's law, plane-polarized light, polaroids and their applications.
This page covers Polarization, chapter 13 of 25 in the Class 12 Physics syllabus set by the National Examination Board (NEB). 3 important questions for this chapter are available, each with a full solution.
For numerical and derivation-based chapters like this one, working through past NEB questions is usually more useful than re-reading notes alone — try solving each important question above before checking the solution, then compare your working step by step.
