Physics - Oscillations

Practise 39 AIIMS previous year questions on Oscillations, compiled from papers spanning 2001 to 2019. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty AIIMS tests.

Oscillations has been asked in 17 of the 19 years of AIIMS papers analysed (2001–2019), with 39 questions in all. 41% of them were easy, 38% moderate and 21% tough. Most of its questions came from 2016, with 5 questions that year. In the last three years (2017–2019) it had 10 questions across 5 papers, about 2 per paper.

The chapter's 6 topics are not weighted equally: Simple Harmonic Motion (14 questions, 36%), Applications of SHM (9 questions, 23%), and Time Period and Frequency (8 questions, 21%) have been asked the most. Simple Harmonic Motion has produced the most tough questions (3).
