Quantum Mechanics Quiz

Quantum mechanics quiz is designed to assess your basic understanding of this field of science and compare your results to everyone who did this questionnaire. QM deals with the behavior of matter on the atomic and subatomic scale, providing the foundation for nuclear physics.

This quantum mechanics quiz uses statistical data to rank your results with everyone else, both globally and regionally. All questions are in the form of images visualizing important concepts in QM, and your task is to figure out which answer accurately describes each visual.

Differences between Quantum Physics and Classical Physics

For those who are new to quantum mechanics, it differs from classical physics in multiple ways. In QM, quantities like energy, momentum and angular momentum are restricted to discrete values, where wave-particle duality means that objects behave as both particles and waves. In addition to that, there are limits to how accurately certain values can be measured, which is widely known as Heisenberg’s uncertainty principle.

Despite this, postulates of quantum mechanics have been experimentally and accurately verified to a great degree. Though QM is generally applied to subatomic scales, in truth, objects of all scales obey the laws of quantum mechanics. Classical physics is just an approximation for the behavior of large systems of objects, which is a more practical approach, because the effects of QM like uncertainty principle become negligent on larger scales, and the complex calculations they involve play no noticeable role on macro scale.

How useful is quantum mechanics?

QM has explained a plethora of the initially unknown features of the universe, like the behavior of the elementary particles that make up all matter in the universe, and how atoms are fused by covalent bonds to form more complicated structures like molecules. Today's technologies for instance work at the scales where quantum effects are significant, like the transistors and semiconductors making up microprocessors or electron microscopes to name the few.

What difficulty level is this quiz?

This quantum mechanics quiz is introductory. You don’t have to be a student of quantum mechanics to successfully complete this test as most of the questions are covered in some of the popular documentaries for wider public. We plan to add an advanced version with far more complex questions in the future.
