Physics is a crucial subject at the higher secondary stage of schooling. Students take up Physics, as a subject in class 11 with the aim of pursuing their career ahead in this field. Physics students can go for further studies and research or pursue professional courses like medicine, engineering, technology after completing schooling. For achieving these aims it’s required that students have a conceptual and strong understanding of Physics subject. So, from class 11, students must start focussing on building the background for Physics.Â The first step into this is knowing the NCERT Class 11 Physics Syllabus. To help students with their studies, we have provided the NCERT Syllabus for Class 11 Physics.

Students can get the detailed NCERT Class 11 Physics Syllabus in PDF format by clicking on the link below. The syllabus PDF contains the units, topics under each unit and no. of periods required to finish a particular unit. Moreover, the PDF also includes NCERT Class 11 Physics Practical Syllabus containing the list of experiments and activities.
