Physics - Oscillations

Practise 31 BITSAT previous year questions on Oscillations, 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.

Oscillations has been asked in 15 of the 16 years of BITSAT papers analysed (2009–2024), with 31 questions in all. 35% of them were easy, 32% moderate and 32% tough. Most of its questions came from 2017, with 4 questions that year. In the last three years (2022–2024) it had 6 questions across 6 papers, about 1 per paper.

The chapter's 6 topics are not weighted equally: Simple Harmonic Motion (14 questions, 45%), Time Period and Frequency (7 questions, 23%), and Applications of SHM (5 questions, 16%) have been asked the most. Simple Harmonic Motion has also led over the last five years, with 4 questions. Simple Harmonic Motion has produced the most tough questions (5).
