Physics - Atomic Physics

Practise 32 VITEEE previous year questions on Atomic Physics, compiled from papers spanning 2006 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.

Atomic Physics has been asked in 16 of the 18 years of VITEEE papers analysed (2006–2024), with 32 questions in all. 59% of them were easy, 31% moderate and 9% tough. Most of its questions came from 2006, with 5 questions that year. In the last three years (2022–2024) it had 4 questions across 3 papers, about 1.3 per paper.

The chapter's 3 topics are not weighted equally: Atomic Spectrum (19 questions, 59%), Bohr's Atomic Model (12 questions, 38%), and Atomic Structure (1 question, 3%) have been asked the most. Atomic Spectrum has also led over the last five years, with 3 questions. Bohr's Atomic Model has produced the most tough questions (2).
