Syllabus, Curriculum - Class 12 Physics

The Nepal Examination Board (NEB) has recently updated the curriculum and syllabus for physics courses in grades 11 and 12. The curriculum is designed to provide students with a general understanding of the fundamental scientific laws and principles that govern scientific phenomena in the world.

It aims to develop the scientific knowledge, skills, and attitudes that are necessary for success at the secondary level, regardless of what students may choose to do after completing their studies. The curriculum is intended to be flexible and adaptable, catering to the diverse aspirations of students who may choose to pursue further studies in science, technical or vocational fields, or other areas.

The syllabus typically covers a range of topics, including mechanics, thermodynamics, waves and optics, electricity and magnetism, and modern physics.

In the mechanics section of the syllabus, students may study topics such as rotational dynamics, periodic motion, and fluid statics. The thermodynamics section may cover the first and second laws of thermodynamics, while the waves and optics section may cover topics such as wave motion, mechanical waves, wave behavior in pipes and strings, and the nature and propagation of light.

The electricity and magnetism section of the syllabus may include topics such as electrical circuits, thermoelectric effects, magnetic fields, and electromagnetic induction. The modern physics section may cover topics such as electrons, photons, semiconductor devices, and quantization of energy.
