Physics - Electromagnetic Waves

Practise 9 JEE Advanced previous year questions on Electromagnetic Waves, compiled from papers spanning 2007 to 2026. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty JEE Advanced tests.

Electromagnetic Waves has been asked in 9 of the 27 years of JEE Advanced papers analysed (2000–2026), with 9 questions in all. 11% of them were easy, 67% moderate and 22% tough. Most of its questions came from 2026, with 1 question that year. In the last three years (2024–2026) it had 3 questions across 6 papers, about 0.5 per paper.

The chapter's 2 topics are not weighted equally: X-Rays (6 questions, 67%) and Electromagnetic Waves and Maxwell's equations (3 questions, 33%) have been asked the most. Over the last five years the most frequent topics have been Electromagnetic Waves and Maxwell's equations (3) and X-Rays (1). X-Rays has produced the most tough questions (1).
