Physics - Electromagnetic Waves
Practise 7 NEST (NISER) previous year questions on Electromagnetic Waves, compiled from papers spanning 2017 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 NEST (NISER) tests.
Electromagnetic Waves has been asked in 5 of the 16 years of NEST (NISER) papers analysed (2011–2026), with 7 questions in all. 29% of them were easy, 71% moderate and 0% tough. Most of its questions came from 2026, with 3 questions that year. In the last three years (2024–2026) it had 4 questions across 4 papers, about 1 per paper.
The chapter's 2 topics are not weighted equally: Electromagnetic Waves and Maxwell's equations (6 questions, 86%) and X-Rays (1 question, 14%) have been asked the most. Electromagnetic Waves and Maxwell's equations has also led over the last five years, with 6 questions.
