Modern Physics

Step into the 20th century and beyond with our Modern Physics resources. Topics include relativity, quantum mechanics, the photoelectric effect, de Broglie waves, and nuclear energy. Students are guided with animated videos, comic-style posters, and problem solutions, while teachers use simulations, experiments, and structured PowerPoints to bring cutting-edge ideas to life. Exam-focused worksheets and tests provide practice with this exciting branch of physics.
