Grade 11 · Physics
This quiz helps revise “Quantum physics” in Physics for grade 11. It has 25 questions in five categories: Light quanta, Light and metal, Atomic spectra, Matter waves, Nuclei and radiation. Questions get harder as the points go up, from 100 to 500.
The 100- and 200-point questions are open here. The rest show only their first words, and there are no answers: all of that is in the game itself.
