Physics - Electromagnetic Waves

Practise 10 BITSAT previous year questions on Electromagnetic Waves, compiled from papers spanning 2009 to 2024. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty BITSAT tests.

Electromagnetic Waves has been asked in 6 of the 16 years of BITSAT papers analysed (2009–2024), with 10 questions in all. 60% of them were easy, 30% moderate and 10% tough. Most of its questions came from 2023, with 3 questions that year. In the last three years (2022–2024) it had 6 questions across 5 papers, about 1.2 per paper.

The chapter's 2 topics are not weighted equally: Electromagnetic Waves and Maxwell's equations (9 questions, 90%) and X-Rays (1 question, 10%) have been asked the most. Electromagnetic Waves and Maxwell's equations has also led over the last five years, with 6 questions. X-Rays has produced the most tough questions (1).
