What does the JEE Main syllabus cover in Electromagnetic Waves?
Displacement current, characteristics and transverse nature of electromagnetic waves, the electromagnetic spectrum and its applications.
Does a high weightage mean Electromagnetic Waves will be asked again?
No. Weightage shows past frequency, not a promise. Use it to prioritise, and practise previous-year questions to see how the chapter is tested.

More JEE Main guides
Counts are compiled from Edurack's JEE Main last five-year analysis (2022–2026) and count questions across all shifts and sessions of each year. Because the number of shifts changes every year, trends compare each chapter's share of the paper among chapters still in the syllabus, not raw counts. Past frequency is a trend guide, not a prediction. Chapters marked "not in syllabus" are absent from NTA's JEE Main 2026 syllabus; always check the latest NTA syllabus before skipping a chapter.
