Physics - Waves and Sound

Practise 14 VITEEE previous year questions on Waves and Sound, compiled from papers spanning 2007 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 VITEEE tests.

Waves and Sound has been asked in 7 of the 18 years of VITEEE papers analysed (2006–2024), with 14 questions in all. 57% of them were easy, 29% moderate and 14% tough. Most of its questions came from 2013, with 4 questions that year. In the last three years (2022–2024) it had 1 question across 1 paper, about 1 per paper.

The chapter's 7 topics are not weighted equally: Interference and Superposition of Waves (7 questions, 50%), Doppler's Effect (2 questions, 14%), and Basics of Mechanical Waves (1 question, 7%) have been asked the most. Over the last five years the most frequent topics have been Basics of Mechanical Waves (1), Doppler's Effect (1), and Stationary waves (1). Doppler's Effect has produced the most tough questions (2).
