Unit-E: Nuclear and Quantum Physics

This page contains MCQs related to Unit E: Structure of an Atom, Atomic models, successes and failures, Photoelectric effect, Matter waves, Compton Scattering, Radioactive decay, fission and fusion reactions and role of these reactions in stellar evolution. These MCQs, sourced from past IBDP Physics papers from 2016 to 2024, are designed to help students reinforce key concepts through varied question types, including calculations, theoretical understanding, and application-based scenarios. Each video explanation provides a step-by-step breakdown, guiding students through complex concepts and problem-solving techniques. By engaging with these resources, students can deepen their comprehension, enhance exam preparedness, and work effectively towards scoring a 7 in IBDP Physics

STRUCTURED QUESTIONS FROM PAST PAPERS

Youtube Links for Complete Video Solutions for Structured questions taken from IBDP Past papers are shown below. The problem notation given below denotes the Concept / Chapter number ( taken from the same chapter names as shown above in MCQs classification ), followed by the year of exam and Actual question number in paper -2 / paper -3. Some questions may belong to more than one chapter and the chapter numbers are also indicated. A brief excerpt of the beginning of the question is also shown below each problem for your reference. 

NOTE: Though most of the questions taken here are from HL papers, there is a significant overlap between SL and HL and in fact, HL questions are covered in depth and hence HL questions are used as a reference.

Happy Learning!
