Physics - Oscillations

Practise 22 COMEDK previous year questions on Oscillations, compiled from papers spanning 2012 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 COMEDK tests.

Oscillations has been asked in 10 of the 15 years of COMEDK papers analysed (2012–2026), with 22 questions in all. 50% of them were easy, 41% moderate and 9% tough. Most of its questions came from 2025, with 5 questions that year. In the last three years (2024–2026) it had 10 questions across 9 papers, about 1.1 per paper.

The chapter's 5 topics are not weighted equally: Simple Harmonic Motion (14 questions, 64%), Applications of SHM (3 questions, 14%), and Time Period and Frequency (3 questions, 14%) have been asked the most. Simple Harmonic Motion has also led over the last five years, with 9 questions. Simple Harmonic Motion has produced the most tough questions (1).
