Physics - Oscillations

Practise 9 IAT (IISER) previous year questions on Oscillations, compiled from papers spanning 2018 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 IAT (IISER) tests.

Oscillations has been asked in 6 of the 9 years of IAT (IISER) papers analysed (2017–2026), with 9 questions in all. 0% of them were easy, 78% moderate and 22% tough. Most of its questions came from 2024, with 3 questions that year. In the last three years (2023–2026) it had 5 questions across 3 papers, about 1.7 per paper.

The chapter's 3 topics are not weighted equally: Time Period and Frequency (5 questions, 56%), Applications of SHM (3 questions, 33%), and Simple Harmonic Motion (1 question, 11%) have been asked the most. Time Period and Frequency has also led over the last five years, with 4 questions. Time Period and Frequency has produced the most tough questions (1).
