In physics, waves and particles seem like complete opposites. And yet, at CERN, we could not explore the incredible world of elementary particles without a thorough understanding of wave physics. This #TeachingTuesday, as we wrap up our series explaining the engineering of the LHC to high-school students, we delve into the physics of everyday waves, discover the strange wave-particle duality of quantum objects, and discuss how radiofrequency cavities rely on waves to accelerate particles at the heart of the LHC. As part of the education portfolio of #CERNScienceGateway, the #CERNSolvayEducation programme was launched by CERN jointly with @SolvayGroup for the #STEMeducation of high-schoolers. It is designed for teenagers who want to go beyond high-school physics and get an introduction to CERN #physics and #technology. In each video, you can test your understanding by answering quiz questions. If you are at least 16 years old, you can enrol for free in the online CERN-Solvay Education Programme towards obtaining a digital certificate, which will allow you to apply for a CERN-Solvay residential student camp.
