Recent Trends in Physics introduces students to selected developments and emerging areas of modern physics. The chapter covers surface and internal seismic waves, including P-waves and S-waves, with reference to earthquake phenomena. It also introduces gravitational waves, nanotechnology and the Higgs boson and their significance in contemporary physics.
This page covers Recent Trends in Physics, chapter 25 of 25 in the Class 12 Physics syllabus set by the National Examination Board (NEB). 4 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.
